  • SPECKLE-BASED IMAGE DISTORTION CORRECTION FOR LASER SCANNING MICROSCOPY
    Publication number: 20240268672
    Abstract: A method of correcting distortion of an image, including: analyzing, by a processor, an image segment of the image to identify a speckle artifact, the image segment being obtained from a scanning imaging device; determining, by the processor, an aspect ratio of a shape of the speckle artifact; determining, by the processor, a correction factor for the shape of the speckle artifact based on the aspect ratio; and adjusting, by the processor, a dimension of the image segment based on the correction factor.
    Type: Application
    Filed: April 15, 2024
    Publication date: August 15, 2024
    Applicant: The General Hospital Corporation
    Inventors: Guillermo J. Tearney, Jiheun Ryu
  • System and method for high-resolution, high-speed capsule endomicroscopy
    Patent number: 12032181
    Abstract: A probe for performing endomicroscopy, including: a light source; a waveguide coupled to the light source; a diffraction grating, the waveguide directing light from the light source to the diffraction grating; and a lens having a first aspheric surface and a second biconic surface, diffracted light from the diffraction grating being directed into the aspheric surface of the lens and being emitted from the biconic surface of the lens towards a transparent cylindrical surface of the probe.
    Type: Grant
