Abstract
An optical data transmission device for providing optical signals containing information data between avionics systems in an aircraft. A fixed optical transceiver array at a first side of a slip ring is in optical communication with a revolving optical transceiver array positioned at a second side of the slip ring. A set of mirrors coated with dielectric material are positioned at the central axis of the slip ring and configured to maintain optical communication between the optical transceiver arrays. The first mirror is fixed at the first side of the slip ring. The second mirror positioned at the second side of the slip ring rotates in concert with the second transceiver array. The mirrors are formed of a material allowing optical signals to be reflected by the mirrors while concurrently allowing a laser beam of an external system to pass through the mirrors and maintain travel along a linear axis.
