    3. A comparative study of noise in supercontinuum light sources for ultra-high resolution optical coherence tomography at 1300 nm

      A comparative study of noise in supercontinuum light sources for ultra-high resolution optical coherence tomography at 1300 nm
      Supercontinuum (SC) light is a well-established technology, which finds applications in several domains ranging from chemistry to material science and imaging systems [1-2]. More specifically, its ultra-wide optical bandwidth and high average power make it an ideal tool for Optical Coherence Tomography (OCT). Over the last 5 years, numerous examples have demonstrated its high potential [3-4] in this context. However, SC light sources present pulse-to-pulse intensity variation that can limit ...

    4. 2nd Canterbury Conference on Optical Coherence Tomography (emphasis on broadband optical sources) September 2017

      2nd Canterbury Conference on Optical Coherence Tomography (emphasis on broadband optical sources) September 2017
      This 3 day conference will be dedicated to recent advances in measurement and imaging conditioned by progress in enlarging the spectrum of the optical source. The larger the bandwidth of the broadband optical source used in spectrometer based OCT, and of the tuning bandwidth of swept lasers used in swept source OCT, the better the axial resolution. However, an increase in the source bandwidth brings with it other problems that ...

    5. Polarization-sensitive plug-in optical module for a Fourier-domain optical coherence tomography system

      Polarization-sensitive plug-in optical module for a Fourier-domain optical coherence tomography system
      In this manuscript we communicate a theoretical study on a plug-in optical module to be used within a Fourier-domain optical coherence tomography system (FD-OCT). The module can be inserted between the object under investigation and any single-mode fiber based FD-OCT imaging instrument, enabling the latter to carry out polarization measurements on the former. Similarly to our previous communication1 this is an active module which requires two sequential steps to perform ...

    6. Master/slave: the ideal tool for coherence revival based optical coherence tomography imaging instruments

      Master/slave: the ideal tool for coherence revival based optical coherence tomography imaging instruments
      In this communication, we present the utility of the Master/Slave (MS) method in combination with the coherence revival technique to obtain full axial range Optical Coherence Tomography (OCT) cross-section images. The MS method eliminates two major drawbacks of the conventional Fourier Transformed (FT) based OCT technology when applied to the coherence revival technique: the need of data re-sampling as well as the need to compensate for unbalanced dispersion in ...

    8. Master/slave based optical coherence tomography for in-vivo, real-time, long axial imaging range of the anterior segment

      Master/slave based optical coherence tomography for in-vivo, real-time, long axial imaging range of the anterior segment
      In this report, we demonstrate that in a coherence revival (CR) based swept source optical coherence tomography (SSOCT) set-up, real-time cross-sectional long-range images can be produced via the Master Slave (MS) method. The total tolerance of the MS method to nonlinear tuning, to dispersion in the interferometer and to dispersion due to the laser cavity, makes the MS ideally suited to the practice of coherence revival. In addition, enhanced versatility ...

    10. Gabor fusion master slave optical coherence tomography

      Gabor fusion master slave optical coherence tomography
      This paper describes the application of the Gabor filtering protocol to a Master/Slave (MS) swept source optical coherence tomography (SS)-OCT system at 1300 nm. The MS-OCT system delivers information from selected depths, a property that allows operation similar to that of a time domain OCT system, where dynamic focusing is possible. The Gabor filtering processing following collection of multiple data from different focus positions is different from that ...

    11. Geometric & radiometric vignetting associated with a 72-facet, off-axis, polygon mirror for swept source optical coherence tomography (SS-OCT)

      Geometric & radiometric vignetting associated with a 72-facet, off-axis, polygon mirror for swept source optical coherence tomography (SS-OCT)
      Optical Coherence Tomography (OCT) has a broad range of applications in 2D and volumetric imaging of micron scale structures typically used on inaccessible objects such as the retina of the eye. This report focuses on Swept Source OCT (SS-OCT), favoured for its faster scanning speeds and therefore faster data acquisition (highly favourable when imaging live patients). SS-OCT relies on the scanning of a narrow laser line at speeds typically in ...

    12. Full-field optical coherence tomography apply in sphere measurements

      Full-field optical coherence tomography apply in sphere measurements
      The geometry of a spherical surface, for example that of a precision optic, is completely determined by the radius of-curvature at one point and the deviation from the perfect spherical form at all other points of the sphere. Full-field Optical Coherence Tomography (FF-OCT) is a parallel detection OCT technique that utilizes a 2D detector array. This technique avoids mechanical scanning in imaging optics, thereby speeding up the imaging process and ...

    13. Master/slave optical coherence tomography imaging of eyelid basal cell carcinoma

      Master/slave optical coherence tomography imaging of eyelid basal cell carcinoma
      Optical coherence tomography (OCT) is fast emerging as an additional non-interventional modality for skin tumor detection and diagnosis. A master/slave flying spot OCT configuration was assembled to detect periocular basal cell carcinomas (BCC). A swept source at 1300 nm and sweeping speed of 50 kHz were used. A three-step process was involved. First, 384 channeled spectra using a mirror were stored for 384 optical path differences at the master ...

    14. Acousto-optic tunable filter for dispersion characterization of time-domain optical coherence tomography systems

      Acousto-optic tunable filter for dispersion characterization of time-domain optical coherence tomography systems
      A broadband supercontinuum light source with an acousto-optic tunable filter (AOTF) are used to characterize dispersion in two time-domain OCT systems, at 850 and 1300 nm. The filter is designed to sweep across two spectral ranges, which are restricted here from 800 to 900 nm and from 1200 to 1500 nm, respectively. Dispersion compensation for 850 nm was achieved with a spectral delay line. Dispersion compensation for 1300 nm was ...

      Method and apparatus for processing the signal in spectral domain interferometry and method and apparatus for spectral domain optical coherence tomography
      Real-time depth measurements in sensing in spectral domain interferometry and for en-face and cross section image production in optical coherence tomography can operate without any need to linearize the data to maximize the output signal and achieve the theoretical depth resolution. Novel interferometry is disclosed, where parameters of a master interferometer dictate the results in a slave interferometer. The master interferometer can be the same measuring interferometer used in two ...
