  • Patent number: 11337604
    Abstract: A method to image an in vivo object in an eye includes illuminating an object in the eye by a light source; configuring one or more detectors to receive light from a conjugate plane behind a confocal plane of the object, the conjugate plane acting as a light screen; receiving at the one or more detectors a backscattered light from the light source which has been refracted at least in part by the object before being backscattered from the light screen to provide a detector data; and processing the detector data over a time period by a computer to generate information about the object.
    Type: Grant

  • Patent number: 10803601
    Abstract: An image processing method for determining and reporting a velocity of a plurality of objects in a space-time image includes: providing an imager to acquire a plurality of images of a line; receiving a plurality of images; generating a space-time image from the plurality of images of the line; applying a mask to a subset image of the space-time image to provide a masked subset area; generating a rotational look up table of intensity values of pixels of columns and rows of the masked subset area; generating a radon transform for each subset image; computing a velocity of a plurality of objects in the subset image based on the radon transform; repeating the step of applying a mask to the step of computing a velocity; and displaying the velocity of a plurality of objects overlaying the space-time image substantially in real-time as the plurality of images are acquired.
