    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 ...

      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. 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 ...

    13. Single all-fiber-based nanosecond-pulsed supercontinuum source for multispectral photoacoustic microscopy and optical coherence tomography

      Single all-fiber-based nanosecond-pulsed supercontinuum source for multispectral photoacoustic microscopy and optical coherence tomography
      We report the usefulness of a single all-fiber-based supercontinuum (SC) source for combined photoacoustic microscopy (PAM) and optical coherence tomography (OCT). The SC light is generated by a tapered photonic crystal fiber pumped by a nanosecond pulsed master oscillator power amplifier at 1064 nm. The spectrum is split into a shorter wavelength band (500800 nm) for single/multi-spectral PAM and a longer wavelength band (800900 nm) band for OCT. In ...

      Master/slave interferometry – ideal tool for coherence revival swept source optical coherence tomography
      In this paper, we demonstrate that the master slave (MS) interferometry method can significantly simplify the practice of coherence revival swept source optical coherence tomography (OCT) technique. Previous implementations of the coherence revival technique required considerable resources on dispersion compensation and data resampling. 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 ...

      Optical module to extend any Fourier-domain optical coherence tomography system into a polarisation-sensitive system
      This article presents a theoretical study on an optical module (OM) that can be inserted between an object under investigation and a Fourier-domain optical coherence tomography system, transforming the latter into a polarisation-sensitive optical coherence tomography optical coherence tomography (OCT) system. The module consists of two electro-optic modulators, a Faraday rotator, a linear polariser and a quarter-wave plate. A detailed description on how the module can be used to extract ...

  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.
