(February 9, 2016) – Used in the company’s Scanning Fiber Endoscope (SFE), McMorrow’s patent (US 9258108) for a closed loop optical feedback synchronization system, provides real time feedback and control of a light emitting fiber when scanning or displaying an image. Unique in the market, the light emitting fiber is driven by an actuator in an angular pattern to scan the image. Light reflected from a lens assembly is received by an optical synchronizer integrated circuit that includes a slot located between walls of the circuit. The reflected light is directed toward a multi-mode fiber in optical communication with the circuit. A radial position of the reflected light as it passes the slot may be used to compensate for a drift in angular velocity of the light emitting fiber.
