    2. High resolution spectral-domain optical coherence tomography using a thermal light source

      High resolution spectral-domain optical coherence tomography using a thermal light source
      Abstract A high resolution spectral-domain optical coherence tomography (SD-OCT) system based on a thermal light source was presented. A novel normalized method was introduced to remove the background noise and the DC noise of the interference spectrum. A Gaussian spectral calibration procedure was performed to improve axial resolution and image quality before reconstructing OCT image. With the proposed method, the quality of the obtained images was greatly improved. Two-dimensional (2D ...

    3. In-vivo full depth of eye imaging spectral domain optical coherence tomography

      In-vivo full depth of eye imaging spectral domain optical coherence tomography
      It is necessary to apply the spectral-domain optical coherence tomography (SD-OCT) to image the whole eye segment for practically iatrical application, but the imaging depth of SD-OCT is limited by the spectral resolution of the spectrometer. By now, no result about this research has been reported. In our study, a new dual channel dual focus OCT system is adopted to image the whole eye segment. The cornea and the crystalline ...

    4. Feature Of The Week 3/6/11: Researchers at Peking University and Shanghai Jiao Tong University Investigate System Tradeoffs for SD-OCT

      Feature Of The Week 3/6/11: Researchers at Peking University and Shanghai Jiao Tong University Investigate System Tradeoffs for SD-OCT
      Feature Of The Week 3/6/11: Although several reviews and reports have described the resolution, probing depth, and signal-to-noise ratio (SNR) of the SD-OCT system, the design and realization of such a system, including the CCD choice, grating parameters and focusing lens for spectrometric detection, is largely dependent on the working experience of the investigator. To the best of our knowledge, there are no reports which discuss how the ...

    5. Evaluation of spectrometric parameters in spectral-domain optical coherence tomography

      Evaluation of spectrometric parameters in spectral-domain optical coherence tomography
      The parameters of the spectrometer were analyzed in order to optimize the performance of spectral-domain optical coherence tomography (SD-OCT). Because probing depth is proportional to spectral resolution, it can be increased with the choice of a higher resolution spectrometer, which implies greater pixel numbers and lower imaging speed, or by sacrificing part of the spectrum, which compromises the axial resolution and side lobes. With a dynamic range of 8 bits ...

    6. Comparison of different focusing systems for common-path optical coherence tomography with fiber-optic bundle as endoscopic probe

      A fiber-optic bundle–based submillimeter probe for endoscopic common-path optical coherence tomography with focusing system is presented. Three different focusing systems, bulk lenses, a gradient index (GRIN) lens, and a microlens array, are proposed and compared. The simulation results show that all the focusing systems can focus the beam with different degrees of effectiveness. The major differences between the different focusing systems exist in the beam size and the divergence ...

    7. Dual channel dual focus optical coherence tomography for imaging accommodation of the eye

      Dual channel dual focus optical coherence tomography for imaging accommodation of the eye
      A dual channel dual focus spectral-domain optical coherence tomography was developed for imaging the accommodation of the eye in real time. The system can provide simultaneous cross-sectional imaging of all the surfaces of the anterior segment of the eye including the cornea, anterior chamber, anterior and posterior surfaces of the crystalline lens. Thus, the modification of the curvatures of the anterior and posterior surfaces of the crystalline lens and the ...
