  • Patent number: 9339182
    Abstract: An eye imaging system, including: a light source module; a radial splitting module; a common optical module; an image receiver; a power supply module for the light source module; a driver module for the image receiver; a processing-displaying module; and a motion driving module. The image receiver is an area array sensor. The motion driving module is connected to the light source module and drives the light source module to move in a radial direction of an upstream illuminating optical path formed by the light source module and the radial splitting module. The image receiver continually opens for exposure in a radial direction of a downstream observation optical path formed by the radial splitting module and the image receiver. The continual opening of the image receiver for signal acquisition is synchronous with the movement of the light source module.

  • Patent number: 8833941
    Abstract: The present patent application discloses a digital slit-lamp microscope system and the methods of the electronic recording and remote diagnosis. The present patent application relates to the field of optical instrument and remote communication control. The purpose is to solve the problems of the electronic recording, reappearing and remote diagnosis of the slit-lamp image. The digital slit-lamp microscope system comprises digital slit-lamp microscope side, communication unit and client side. The digital slit-lamp microscope side includes a build-in slit-lamp microscope and is connected to the communication unit and the client side in sequence. The digital slit-lamp microscope side irradiates the eyes of the patient, and then transmits the pathology information of the eyes of the patient to the communication unit and the client side in sequence.
