    2. An overview of methods to mitigate artifacts in optical coherence tomography imaging of the skin

      An overview of methods to mitigate artifacts in optical coherence tomography imaging of the skin
      Background Optical coherence tomography (OCT) of skin delivers three-dimensional images of tissue microstructures. Although OCT imaging offers a promising high-resolution modality, OCT images suffer from some artifacts that lead to misinterpretation of tissue structures. Therefore, an overview of methods to mitigate artifacts in OCT imaging of the skin is of paramount importance. Speckle, intensity decay, and blurring are three major artifacts in OCT images. Speckle is due to the low ...

    3. Q-switch-pumped supercontinuum for ultra-high resolution optical coherence tomography

      Q-switch-pumped supercontinuum for ultra-high resolution optical coherence tomography
      In this Letter, we investigate the possibility of using a commercially availableQ-switch-pumped supercontinuum (QS-SC) source, operating in the kilohertz regime, for ultra-high resolution optical coherence tomography (UHR-OCT) in the 1300nm region. The QS-SC source proves to be more intrinsically stable from pulse to pulse than a mode-locked-based SC (ML-SC) source while, at the same time, is less expensive. However, its pumping rate is lower than that used in ML-SC sources ...

    4. Passive optical module for polarization-sensitive optical coherence tomography systems

      Passive optical module for polarization-sensitive optical coherence tomography systems
      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 ...

    6. En-face time-domain optical coherence tomography with dynamic focus for high-resolution imaging

      En-face time-domain optical coherence tomography with dynamic focus for high-resolution imaging
      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

      Effects of Temperature Variations during Sintering of Metal Ceramic Tooth Prostheses Investigated Non-Destructively with Optical Coherence Tomography
      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 ...

    9. 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 ...

    10. 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 ...

    11. 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 ...

    12. 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 ...

    14. 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 ...

  2. About Adrian G. Podoleanu

    Adrian G. Podoleanu

    Adrian G. Podoleanu is the head of Applied Optics Group and Professor of Biomedical Optics at the University of Kent at Canterbury. Adrian Podoleanu has joined the Applied Optics Group in January 1993 as a Tempus Fellow and then worked as a Research Associate since Sept. 1993. Up to 1992, he was associate professor in the Technical University Bucharest, Romania, where he taught Physics, Optics and optoelectronics and developed research on Lasers and fast optoelectronics. He was involved in Kent in research and development of a subnanosecond dwell time multichannel digital correlator (the fastest multichannel configuration), in distance measurements using white light interferometry, Faraday sensing and secure optical communications. Since 1995 he is been working in the optical coherence tomography (OCT) field for imaging eye and skin and flow characterisation. He contributed towards development of the en-face OCT imaging as a new technology to complement the more conventional longitudinal OCT imaging. For the first time, he generated dual OCT and confocal images of the retina. He is co-author of more than 150 journal papers and conference proceedings and of 13 patents on the above mentioned subjects. In 1984, he was awarded The Romanian Academy "Constantin Miculescu" prize for research in Lasers and Nonlinear Optics.
