  • EASY TO MANUFACTURE AUTOCLAVABLE LED FOR OPTICAL TRACKING
    Publication number: 20230210607
    Abstract: An optical tracking system is provided. The optical tracking system comprises an autoclavable fiducial marker assembly including an opaque housing, a light source, a window panel configured to refract light rays from the light source therethrough, and a metallized coating forming a hermetic seal at an interface of the window panel and the opaque housing. The fiducial marker assembly is configured to shield a peripheral edge of the window panel from the light rays. The system further comprises a tracking device comprising at least two optical sensors configured to detect a position of a light ray emitted by the light source. The system further comprises a processor configured to receive the position of the light rays from the optical sensors, shift the position of each light ray based on a calculated refraction deviation, and triangulate the location of the light source based on the shifted position of each light ray.
    Type: Application
