Abstract
A closed loop, optical feedback synchronization system provides real time feedback and control of a light emitting fiber when scanning or displaying an image. 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.
