2. Passive optical module for polarization-sensitive optical coherence tomography systems
  
  Explore OSA | OSA Publishing Jun 20 2017
  
  The paper presents a proof-of-concept polarization-sensitive swept source optical coherence tomography (OCT) system that performs measurements of the retardance as well as of the axis orientation of a linear birefringent sample. The system performs single input state polarization-sensitive OCT and employs an optical module based on optically passive elements such as two beam displacers and a Faraday rotator. Our implementation of the PS-OCT system does not need any calibration step ...

3. High Throughput Photonic Time Stretch Optical Coherence Tomography with Data Compression
  
  Explore IEEE Xplore Jun 17 2017
  
  Photonic time stretch enables real time high throughput optical coherence tomography (OCT), but with massive data volume being a real challenge. In this paper, data compression in high throughput optical time stretch OCT has been explored and experimentally demonstrated. This is made possible by exploiting spectral sparsity of encoded optical pulse spectrum based on compressive sensing (CS) approach. Both randomization and integration have been implemented in the optical domain avoiding ...

6. En-face time-domain optical coherence tomography with dynamic focus for high-resolution imaging
  
  Explore SPIE | Journal May 28 2017
  
  Optical coherence tomography (OCT) is capable of imaging microstructures within translucid samples. A time-domain version of the OCT technology is employed here due to its compatibility with the dynamic focus (DF) procedure. DF means moving the confocal gate in synchronism with the depth scanning via the coherence gate. A DF-OCT setup was implemented for imaging samples at 1300 nm. Its confocal gate of 180 m 180m allows the achievement of ...

7. Effects of Temperature Variations during Sintering of Metal Ceramic Tooth Prostheses Investigated Non-Destructively with Optical Coherence Tomography
  
  Explore MDPI Open Access Journals Platform May 26 2017 Dentistry
  
  Calibration loss of ovens used in sintering metal ceramic prostheses leads to stress and cracks in the material of the prostheses fabricated, and ultimately to failure of the dental treatment. Periodic calibration may not be sufficient to prevent such consequences. Evaluation methods based on firing supplemental control samples are subjective, time-consuming, and rely entirely on the technicians skills. The aim of this study was to propose an alternative procedure for ...

8. Scalable Parallel Optimization of Digital Signal Processing in the Fourier Domain (Thesis)
  
  Explore Welcome to Kent Academic Repository Apr 4 2017 Student Theses
  
  The aim of the research presented in this thesis is to study different approaches to the parallel optimization of digital signal processing algorithms and optical coherence tomography methods. The parallel approaches are based on multithreading for multi-core and many-core architectures. The thesis follows the process of designing and implementing the parallel algorithms and programs and their integration into optical coherence tomography systems. Evaluations of the performance and the scalability of ...

10. A comparative study of noise in supercontinuum light sources for ultra-high resolution optical coherence tomography at 1300 nm
  
  Explore Conference Proceedings Mar 18 2017 Broadband Sources
  
  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 ...

11. 2nd Canterbury Conference on Optical Coherence Tomography (emphasis on broadband optical sources) September 2017
  
  Explore 2ccoct.aogkent.uk Mar 16 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 ...

12. Polarization-sensitive plug-in optical module for a Fourier-domain optical coherence tomography system
  
  Explore Conference Proceedings Mar 1 2017
  
  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 ...

13. Master/slave: the ideal tool for coherence revival based optical coherence tomography imaging instruments
  
  Explore Conference Proceedings Feb 23 2017
  
  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 ...

15. Master/slave based optical coherence tomography for in-vivo, real-time, long axial imaging range of the anterior segment
  
  Explore Conference Proceedings Feb 14 2017 Ophthalmology
  
  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 ...
