  • Patent number: 11986243
    Abstract: Disclosed is a fundus camera, which relates to the technical field of medical devices and includes: an illumination module, a main optical assembly, a focusing module, and an image sensing acquisition module; the illumination module includes a plurality of light sources configured to emit light of different wavelengths, illumination light emitted by the plurality of light sources is conducted to enter an eye of a patient through the main optical assembly, and light reflected by a retina of the patient is conducted to pass through the main optical assembly and the focusing module to enter the image sensing acquisition module. The fundus camera provided by the present application improves the technical problem that the fundus camera in the prior art cannot image different layers of the retina, thereby providing valuable medical and diagnostic data.

  • Publication number: 20210127051
    Abstract: A vehicle in-cabin monitoring system is disclosed. For one embodiment, the system includes a sensor module, the sensor module includes a plurality of image sensors (e.g., cameras). The system includes a first illumination source. The system includes a signal generator to generate a sync signal to sync a first and a second of the plurality of image sensors to monitor an interior cabin of a vehicle, where the sync signal is to synchronize the first illumination source to the first image sensor such that objects illuminated by the first illumination source is not captured by the second image sensor while allowing the first image sensor to capture objects illuminated by the first illumination source. For another embodiment, one or more captured images are fused together.

  • Patent number: 10792101
    Abstract: A method and system of ablating melanin are provided. Stepwise multi-photon fluorescence is induced in melanin within a region of tissue. The fluorescence is detected, and at least a portion of the melanin from which the fluorescence is detected is ablated. The system and method can use a continuous wave laser in the near infrared range for the inducement and ablation of melanin, providing high resolution at low cost.
