Apparatus for optical communication using a large-area primary reflector

摘要

An optical transceiver includes an opaque element having a concave reflective surface arranged in a path of each of an outgoing and an incoming light signal, the reflective surface configured to redirect the paths of the respective light signals. An optical detector is arranged facing the reflective surface. The optical detector is configured to detect a redirected incoming light signal from the reflective surface and to generate therefrom a receive signal proportional to the incoming light signal. An emitter is arranged facing the reflective surface. The emitter is configured to generate the outgoing light signal proportional to a transmit signal. A lens assembly is arranged between the reflective surface of the opaque element and both the optical detector and the emitter. The lens assembly is configured to couple the redirected incoming light signal to the optical detector and to couple the outgoing light signal to the reflective surface.
