    2. Angiographic Imaging of an In Vivo Mouse Brain as a Guiding Star for Automatic Digital Refocusing in OCT

      Angiographic Imaging of an In Vivo Mouse Brain as a Guiding Star for Automatic Digital Refocusing in OCT
      A method allows the extraction of the recovery factor that maximizes the image contrast of OCT (optical coherence tomography) and/or OCTA (OCT angiography) of a living subject is proposed in this study. Due to the finite depth of focus in imaging optics, the volume OCT imaging suffers from blurriness in the lateral resolution. By utilizing the digital hologram method or angular spectrum method, the blurred image can be refocused ...

    3. The refractive index measurement technique based on the defocus correction method in full-field optical coherence tomography

      The refractive index measurement technique based on the defocus correction method in full-field optical coherence tomography
      We propose and demonstrate a novel refractive index (RI) measurement by using the numerical-sample-motion based the defocus correction method in full field optical coherence tomography (FF-OCT). Overcoming the general problem in FFOCT that is the position of the focal plane is separated from the position of the image plane when imaging a deep region inside a sample, we measure the separation distance from the position of the focal plane to ...

    4. Feature Of The Week 3/27/11: Feasibility of Full-Field Optical Coherence Tomography for Detection of Counterfeit Paper Money

      Feature Of The Week 3/27/11: Feasibility of Full-Field Optical Coherence Tomography for Detection of Counterfeit Paper Money
      Feature Of The Week 3/27/11: This week’s featured work is from Gwangju Institute of Science and Technology (GIST) where researchers reported on an exciting application of full-field optical coherence tomography (FF-OCT) for identifying counterfeit bank notes. Recent application of the FF-OCT has been expanded to medical biology, clinical pathology, cell biology, material industry and even biometric-based forensic science. In this study, they have demonstrated new approach of ...
