Telesto Series Polarization-Sensitive OCT (PS-OCT) Systems preserve, detect, and process polarization information of samples through noninvasive, subsurface optical imaging. This technology can uncover normally unobserved features of birefringent samples (e.g. tissue, plastic, or crystals) that stem from the internal microstructure. For example, scar tissue will interact differently with polarized light than regular skin tissue, so the polarization information can be used to add an additional layer of contrast to a standard optical coherence tomography (OCT) image. This additional layer can be characterized as the cumulative retardation, optic axis, or degree of polarization uniformity (DOPU).

OCT is an optical imaging technique that produces real-time, 2D cross-sectional and 3D volumetric images of a sample. This technique provides structural information about the sample based on light backscattered from different layers of material within that sample, producing images with micron-level resolution and millimeters of imaging depth. In addition to high resolution, the non-contact, noninvasive nature of OCT makes it well suited for imaging samples such as biological tissue, small animals, and industrial materials.

The Telesto PS-OCT systems use an incident beam of known polarization and a dual-detector design to incorporate polarization information in 2D cross-sectional and 3D volumetric images of a sample. OCT is typically performed with an incident beam of unknown polarization and a single detector unit. The Telesto PS-OCT systems control the polarization incident on the sample and reflected in the reference arm of the interferometer by using two carefully aligned wave plates. The preserved polarization information is then measured using two detectors (see the PS-OCT Tutorial tab).

These OCT systems provide the flexibility required for long-range and high-resolution imaging applications. The detector unit is housed in the same box as the standard Telesto systems and features the same robustness as all Thorlabs OCT systems. No calibration or adjustment is needed after shipping or during use. The compact design of the system allows for easy and mobile operation. The 64-bit software pre-installed on the included computer displays and processes 2D and 3D OCT data in real time. Optional accessories are available below to customize your OCT system to meet the requirements of your application. Additionally, Thorlabs offers two complete, preconfigured OCT systems for 1300 or 1325 nm based on the components sold on this page.

The components below can also be used to upgrade your existing Thorlabs OCT system with additional features and are compatible out of the box with the Thorlabs' OCT systems and accessories sold below. While most systems are upgradable, we recommend contacting the OCT Team to determine the optimal solution for your system and intended application.

Polarization-Sensitive OCT

With Thorlabs' Telesto Series Polarization-Sensitive OCT (PS-OCT) Imaging Systems, it is possible to obtain additional information carried by the polarization state of light that has interacted with a sample. When incident light with a defined polarization state is used, changes in the polarization state resulting from the sample can be interpreted. Birefringent material causes a relative delay between two orthogonal polarization states known as phase retardation. This relative delay has an orientation, called the optic axis, which can be visualized with polarization-sensitive OCT. Additionally, the sample can have properties which depolarize the incident polarized light, resulting in an arbitrary polarization state of the light that can be characterized by the degree of polarization uniformity (DOPU). Both these behaviors can be detected with the Telesto PS-OCT systems.

PS-OCT System Schematic

System Design

A Telesto PS-OCT system is a phase-stable spectral domain OCT system. It is a single-input device with a unique polarization-sensitive detector unit for simultaneous acquisition of two orthogonal polarization states at full imaging speed. The Telesto PS-OCT system is designed to define the polarization state of light incident on the sample and preserve polarization throughout the system, as shown in the schematic to the right. Starting with linearly polarized light from the superluminescent diode light source, two quarter-wave plates, one in the reference arm and one in the sample arm, are used to alter the polarization state of the light. In the reference arm, the quarter-wave plate has a 22.5° orientation relative to the linearly polarized input; the beam passes through the wave plate twice, so light exits the reference arm with a 45° linear polarization relative to the input light. In the sample arm, the quarter-wave plate is oriented at 45° relative to linearly polarized input light, converting it into circularly polarized light that is incident on the sample. The orientation of these two wave plates enables the system to be as polarization sensitive as possible. In addition to the wave plates, specially designed optical components maintain polarization throughout the whole system.

The detection of two polarization states does not slow down the acquisition rate when compared to the standard TEL211 and TEL221 systems, allowing the same imaging speeds to be achieved. The system was designed with robustness and easy handling in mind. No calibration of the polarization-sensitive detector unit is necessary at any time, as expected from a true turnkey OCT system. The result is a polarization-sensitive OCT system that yields highly reproducible measurements.

Signal Processing

The two individual OCT images from the unique polarization-sensitive detector unit can be shown separately or combined in a total intensity image. Some samples, e.g. scotch tape, may produce changes in polarization state that cause extinction banding. Since the two sensors receive light with orthogonal linear polarizations, the extinction bands will appear in different locations in each image. The total intensity image provides the advantage of eliminating this banding, leading to a better OCT image compared to standard OCT systems.

Total Intensity Image: The information of both sensors is combined, producing an optimized OCT image without the banding.

To obtain polarization images, the combination of the information from both sensors (red box in the figure below) is necessary. The information provided by two orthogonal polarization states of interfered light enables the calculation of the Stokes vectors (I, Q, U, V) for each image point. Each one of these values (I = Total Intensity) may be imaged individually, as shown in the purple box in the figure below. In addition, the Stokes vectors describing the polarization state of light can be used to determine several more advanced polarization measurements. As shown in the blue box in the figure below, cumulative retardation, optic axis, or degree of polarization uniformity (DOPU) may be calculated. Example images of tape are shown in the figure below (click each box to enlarge).

A roll of tape is imaged with Thorlabs’ PS-OCT system using orthogonal polarization information from two sensors to calculate Stokes vectors, which are then used to calculate cumulative retardation, optic axis, or DOPU. With our software, it is possible to see all the images shown in the figure separately. For detailed information, please see the Software tab.

Dataset Management

ThorImageOCT provides advanced dataset management capabilities, which allow several datasets to be opened simultaneously. Datasets are uniquely defined using an identifier consisting of a study (or test series) name and an experiment number. Grouping of datasets can be achieved by using the same study name. The "Captured Datasets" list shows an overview of all open datasets, including the dataset identifier, the acquisition mode, and preview pictures of the still video image and the OCT data.

Datasets can be exported in various image formats, such as PNG, BMP, JPEG, PDF, or TIFF. The set can also be exported in complete data formats suited for post-processing purposes, such as RAW/SRM, FITS, VTK, VFF, and 32-bit floating-point TIFF.

The OCT file format native to ThorImageOCT allows OCT data, sample monitor data, and all relevant metadata to be stored in a single file. ThorImageOCT can also be installed and run on computers without OCT devices in order to view and export OCT data. The user has full access to the raw and processed data from the device, including additional data used for processing, e.g. offset errors.

Acquired OCT datasets can also be exported and modified in a third-party program, and then reimported back into the ThorImageOCT software. This functionality allows for fast and customized modifications of OCT images, while still using the dataset management of the ThorImageOCT software. As shown in the example to the right, OCT data (left) can be exported to ImageJ and a smoothing filter applied in the lateral direction (center). Using the "External Program" button allows the modified data to be reimported into ThorImageOCT for further analysis. For example, the peak detection tool can be used to measure the layer thicknesses (right).

Imaging Modes

Different OCT imaging modes can be selected using the mode selector. If the ThorImageOCT software finds a compatible system connected and switched on, all operational modes will be selectable. If no OCT device is present, only the data viewing mode for viewing and OCT data export will be available.

In the Polarization-Sensitive OCT (PS-OCT) system, two additional imaging modes are available and the 1D mode is augmented to show each camera's spectra simultaneously. The combination of both cameras, and therefore the unique additional information of the PS-OCT system, is implemented in the 2D and 3D Polarization-Sensitive Imaging Modes.

2D Mode

In the 2D imaging mode, the probe beam scans in one direction, acquiring cross-sectional OCT images which are then displayed in real time. Line averaging before or after the Fast Fourier Transform (FFT) is available, as well as B-Scan averaging. For long term measurements, a time series function, which has an adjustable time interval between two acquisitions, is included. Image display parameters, such as color mapping, can be controlled in this mode. We have also implemented an option for automatic calculation of the optimum contrast and brightness of the displayed OCT images.

2D Polarization-Sensitive Mode

The 2D polarization-sensitive imaging mode acquires cross-sectional OCT images and displays them in real time. It has two configurable displays, each able to show one of the following images: a single camera's intensity, a combination of both cameras' intensities, or polarization data such as retardation, optic axis, DOPU or a single Stokes parameter. To improve the image quality or allow for variable acquisition time, several averaging parameters and adjustable line rates are implemented. Image display parameters, such as color mapping or thresholding, can be controlled in this mode. We have also implemented an option for automatic calculation of the optimum contrast, brightness and thresholding of the displayed OCT images which operates on the intensity and PS-OCT images.

3D Mode

In the 3D imaging mode, the OCT probe beam scans sequentially across the sample to collect a series of 2D cross-sectional images which are then processed to build a 3D image.

To accommodate long term measurements, a time series function that takes a series of 3D measurements is available. The number of volumes to be acquired and the time interval between scans are adjustable.

In the ThorImageOCT software, 3D volume datasets can be viewed as orthogonal cross-sectional planes (see below) and volume renderings.

The Sectional View features cross-sectional images in all three orthogonal planes, independent of the orientation in which the data was acquired. The view can be rotated as well as zoomed in and out.

The Rendering View provides a volumetric rendering of the acquired volume dataset. This view enables quick 3D visualization of the sample being imaged. Planes of any orientation can be clipped to expose structures within the volume. The 3D image can be zoomed in and out as well as rotated. Furthermore, the coloring and dynamic range settings can be adjusted.

Utilizing the full potential of our high-performance software in combination with our high-speed OCT systems, we have included a Fast Volume Rendering Mode in the ThorImageOCT software, which serves as a preview for high-resolution 3D acquisitions. In this mode, high-speed volume renderings can be displayed in real-time, providing rapid visualization of samples in three dimensions.

3D Polarization-Sensitive Mode

The 3D polarization-sensitive imaging mode extends the 3D imaging mode. The acquisition and display options are the same as in the 3D imaging mode. Additionally, the user can choose to display one of the following rendered volume imaging options: an intensity OCT image (from either a single camera or the combination of both) or a PS-OCT image (such as retardation, optic axis, DOPU or one of the three Stokes parameters). The rendered PS-OCT images can be adjusted with a threshold computed out of the intensity OCT image to only display the polarization-sensitive data of regions above the noise.

ThorImage OCT includes a Fast Volume Rendering mode, which serves a preview for high-resolution 3D acquisitions of intensity and PS-OCT images. In this mode, high-speed volume renderings can be displayed in real time, providing rapid visualization of samples in three dimensions.

OCT Doppler Imaging Screen Shot

Doppler Mode

Doppler OCT imaging comes standard with all OCT systems. In the Doppler mode, phase shifts between adjacent A-scans are averaged to calculate the Doppler frequency shift induced by particle motion or flow. The number of lateral and axial pixels can be modified to change velocity sensitivity and resolution during phase shift calculation. The Doppler images are displayed in the main window with a color map indicating forward- or backward-directed flow, relative to the OCT beam.

OCT Speckle Variance Imaging Screen Shot
Click to Enlarge

Speckle Variance Mode

The speckle variance imaging mode is an acquisition mode which uses the variance of speckle noise to calculate angiographic images. It can be used to visualize three dimensional vessel trees without requiring significant blood flow and without requiring a specific acquisition speed window. The speckle variance data can be overlaid on top of intensity pictures providing morphological information. Different color maps can be used to display the multimodal pictures.

Externally-Triggered Acquisition

ThorImageOCT and the SDK APIs provide the ability to externally trigger the acquisition of A-Scans. This enables the user to synchronize measurements from different modalities (e.g. vibrometry and synchronized positioning) with an OCT measurement. Synchronization is greatly simplified with all current CameraLink-based Thorlabs OCT systems (a TTL level trigger signal source required). External triggering is available for all imaging modes and can be toggled in the settings dialog in ThorImageOCT.

Thorlabs' current generation of Ganymede (Item # GAN6x1) and Telesto (Item #s TELxx1 & TELxx1PS) SD-OCT Systems include an external B-Scan trigger for synchronization with other experiments.

The analog signal from another data source (i.e., fluorescence signal) is sampled and displayed simultaneously with the OCT signal.

 

 

Software Development Kits

For maximum flexibility, customized solutions can be implemented in ThorImageOCT using software development kits (SDKs). Experienced software developers can use these in a multitude of programming environments to tailor the use of Thorlabs OCT systems to their specific application. SDKs are available in:

  • ANSI C with C++ Demo Programs
  • LabVIEW® Including Demo Programs and Advanced Sample Code

I'm Sejong Chun, working at the Fluid Flow Group in KRISS, South Korea. (It is a metrology institute in South Korea.) I would like to just learn whether such an OCT system can measure flow velocity as well as fluid viscosity. 1) flow velocity measurement in a micro channel 2) fluid viscosity measurement in the micro channel with Non-Newtonian fluids (shear thinning and shear thickening fluids) by birefringence. Thank you for your kind comments.
nreusch  (posted 2020-01-28 05:33:58.0)
Dear Sejong Chun, Thank you for your provided feedback. In the following, we will reply on your specific questions: 1.) In fact, our OCT systems are able to measure flow velocities of fluids via the functional Doppler Acquisition Mode that is included within our OCT software application. 2.) The TEL220PSC2 OCT system can visualize birefringent layers, e.g. by determining the phase retardation between two orthogonally polarized states of the back-scattered OCT light. Please do not hesitate to contact us at OCT@thorlabs.com, if you have any further questions. Best regards, Your Thorlabs OCT Applications Team

OCT Base Units (Required OCT System Component)

Scanning System and Scan Lens Kit Required
To be functional, an OCT system build must include a base unit, a scanning system, and a scan lens kit.
  • 1300 nm or 1325 nm Center Wavelength Options
    • 1300 nm, High Resolution: 3.5 mm Imaging Depth and 5.5 µm Resolution in Air
    • 1325 nm, Long Range: 7.0 mm Imaging Depth and 11 µm Resolution in Air
  • Each Base Unit has Four A-Scan Rates for Flexibility in Imaging Speed and Sensitivity
    • 5.5 kHz to 76 kHz A-Scan Rate; 109 dB Max Sensitivity
  • Fully Configurable Trigger for Easy Integration into Larger Experiments
  • Analog Input for Combining Other Data Sources with the OCT Signal
  • Internal Hardware Diagnostics for Improved Troubleshooting

The imaging performance of any OCT system is largely dependent on the design and components incorporated into the base unit. All of Thorlabs’ OCT base units include an OCT engine, high-performance computer, pre-installed software, and a software development kit (SDK).  For a fully operational system, one scanning system and a scan lens kit (both sold separately below) must be purchased along with a base unit.

For the Telesto Polarization-Sensitive OCT Base Units, the engine is comprised of a superluminescent diode light source, scanning electronics, and a polarization-sensitive detection module (see the PS-OCT Tutorial for more information). These base units are capable of operating at A-Scan rates up to 76 kHz and offers a maximum sensitivity of 109 dB at 5.5 kHz. The engine and detection components are integrated into a 411.8 mm x 325.0 mm x 143.0 mm (16.21" x 12.80" x 5.63") housing. 

For synchronization with other experiments, two analog inputs are included on the base units; this allows other data sources to be combined or overlayed with the OCT signal. The OCT base units also feature a fully configurable trigger that is extensively programmable in our ThorImage®OCT software. The trigger can be operated as either an input, responding to external signals, or an output, generating trigger signals. Trigger signals can be sent at the start of each A-, B-, or volume scan, as well as after an arbitrary number of scans.

Deep-Imaging Base Unit
The TEL211PS Deep-Imaging Base Unit is designed using an SLD1325 superluminescent diode that provides over 100 nm of spectral bandwidth and enables the base unit to achieve a very high 7.0 mm imaging depth with 11 µm of axial imaging resolution in air. For these reasons, this base unit is the ideal choice for long-range imaging of highly-scattering samples in an air medium. 

High-Resolution Base Unit
The TEL221PS High-Resolution Base Unit features Thorlabs' highest resolution OCT imaging capability at 1300 nm. An ideal choice for high-resolution imaging in scattering samples, these base units utilize Thorlabs' unique matched-pair superluminescent diodes for over 170 nm of bandwidth that translates to 5.5 μm axial resolution at an imaging depth of 3.5 mm in air.

  • Scan an OCT Light Source Beam Across a Sample to Acquire 2D or 3D Images
  • Two Available Options:
    • Standard Scanner for High Stability and Ease-of-Use
    • User-Customizable Scanner with Open Construction for Customization of Scan Path

OCT scanning systems scan the OCT light source beam across a sample for 2D cross-sectional and 3D volumetric imaging. OCT applications can vary widely, from live animal imaging to industrial materials analysis, with each requiring a different set of scanning parameters. We currently offer two types of beam scanning systems for use with our Telesto polarization sensitive base units: standard and user-customizable.

Each scanner contains an OCT interferometer with a sample arm and a reference arm. The reference arm of the OCT interferometer is placed near the sample and housed within the scanning system itself to guarantee the phase stability of the sample arm relative to the reference arm. To account for different sample distances and reflectivities (e.g., while imaging through water), the reference arm path length, as well as the reference arm intensity, is user-adjustable. To minimize image distortion caused by dispersion, our OCT systems are designed to optically match the reference and sample arm lengths to the greatest extent possible. Dispersion effects from the sample (e.g., imaging through water or glass) can be compensated for using the included ThorImage OCT software.

The scanner is equipped with an integrated camera that can obtain real-time en face video of the sample during OCT measurements when used with our ThorImage OCT software (see the Software tab for details). Illumination of the sample is provided by a ring of user-adjustable white light LEDs around the exit aperture of each scanner.

The specialized PS-OCT scanners contain two additional quarter-wave plates (compared to the SD-OCT scanners), which are necessary to obtain polarization images. Since the interference of light depends on its polarization state, it is necessary to change the polarization state of the light in the reference arm to be sensitive to all possible polarization states of the light in the sample arm. Hence, one quarter-wave plate is located in the reference arm and a second quarter-wave plate is located in the sample arm to create a polarization state which leads to a maximum contrast in the polarization images. Please see the PS-OCT Tutorial tab for more details.

PS-OCT Standard Scanner
The OCTG13 PS-OCT Standard Scanner is ideal for imaging applications that require a stable, easy-to-operate setup. The entire design of the standard scanner is contained within a rugged, light-tight housing that minimizes the risk of misalignment. For precise measurements and fine adjustments of the reference arm length, a micrometer screw is located at the top of the standard scanner. A reference length adapter, which must be purchased separately, is required for this scanner.

PS-OCT User-Customizable Scanner
The OCTP-1300PS(/M) User-Customizable Scanner is designed with an open construction to enable easy customization of the optical beam path using Thorlabs' standard optomechanical components. This scanner features SM1 (1.035"-40) ports and 4-40 tapped holes at several locations that allow mounting of SM1-threaded or 30 mm cage-compatible components, respectively. The scan lens port is directly compatible with either M25 x 0.75 or SM1-threaded components, and can be converted to other thread standards, such as RMS (0.800"-36) via our selection of thread adapters. Additional scanning and non-scanning optical input/output ports are available for integration of a laser for fluorescence excitation or additional sample illumination.

Z-Spacers for the OCTP-13300PS(/M) and OCTG13PS Scanners
  • Sample Z-Spacers Position Scanner at Optimal Working Distance From Sample
  • Ring (Air) and Immersion (Liquid) Z-Spacers Available

Thorlabs offers both ring and immersion style sample Z-spacers that enable optimal positioning of a scanning system relative to the sample. The OCT-AIR3, OCT-IMM3, and OCT-IMM4 Z-Spacers feature knurled rings that allow the spacing distance to be adjusted and locked in place for increased stability. Several Z-spacer options are available; please see the table below for compatibility with our scanners and lens kits.

Our ring-style Z-spacers provide a distance guide between the scanner and sample. The sample is in contact with the ring-shaped tip of the spacer and should only be used when air is the scanning medium. In contrast, our immersion spacers are equipped with a glass plate that contacts the sample surface within the scanning area. Unlike the ring-style spacers, immersion spacers enable access to samples contained within a liquid environment while also providing sample stabilization. Better index matching and a tilted glass plate also help reduce strong back reflections from the sample surface and enhances the contrast of the image.

Precise translation and rotation are often required for optimal positioning of a sample before and during OCT imaging. The OCT-XYR1(/M) is an XY linear translation stage with a rotating platform and solid plate for sample mounting and easy cleaning. The OCT-XYR1 or OCT-XYR1/M stage can be secured to the OCT-STAND or OCT-STAND/M, respectively, using the 1/4" (M6) counterbores at the corners. The top plate is removable for access to 4-40, 8-32 (M4), and 1/4"-20 (M6) tapped holes and an SM1-threaded (1.035"-40) central hole for mounting optomechanical components. The XYR1A Solid Sample Plate can be purchased separately as a direct replacement for the top plate. 

The X and Y micrometers offer 1/2" (13 mm) of travel with graduations every 0.001" (10 µm). The stage's rotation and translation can be freely changed without compromising the stability of attached components. An engraved angular scale along the outer edge of the stage's rotating platform allows the user to set the angular orientation of the stage, which can then be fixed using the 5/64" (2 mm) hex locking setscrew. Locking the rotation of the stage does not prevent XY translation using the actuators.
