  • Fluorescein fluorescent fundus angiography device employing polarizing beam splitter and linear polarizing filter
    Patent number: 11779211
    Abstract: Disclosed is a fluorescent fundus camera which is one kind of ophthalmological diagnostic equipment, using a blue excitation light beam when a contrast medium appears in the retinal vessels. When an abnormal blood vessel is present, the contrast medium leaks into the retina or appears as color in tissues surrounding the retina, and the presence of damage to the retina and the appearance of abnormal neovascularization can be found.
    Type: Grant
    Filed: March 13, 2019
    Date of Patent: October 10, 2023
    Assignee: AIINSIGHT INC.
    Inventors: Hanjo Kwon, Keun Heung Park
  • DEEP LEARNING ARCHITECTURE SYSTEM FOR AUTOMATIC FUNDUS IMAGE READING AND AUTOMATIC FUNDUS IMAGE READING METHOD USING DEEP LEARNING ARCHITECTURE SYSTEM
    Publication number: 20220189012
    Abstract: Disclosed are an algorithm for automatic fundus image reading, and a deep learning architecture for automatic fundus image reading, which are capable of minimizing the amount of data required for learning by training and reading artificial intelligence in a manner similar to that of an ophthalmologist who acquires medical knowledge.

  • Polarization fundus camera for effectively suppressing internal reflection
    Patent number: 11058298
    Abstract: Disclosed is a polarization fundus camera including: an illumination unit emitting light; a diffusion lens; an illumination lens irradiating the light introduced from the diffusion lens; a mirror reflecting light introduced from the illumination lens; a polarization beam splitter; an objective lens enlarging an image of a fundus formed by the light introduced from the polarization beam splitter; a short-range eyepiece lens reducing an image of the fundus enlarged by the objective lens; a linear polarization filter; a narrowband optical filter; and an imaging device.
