摘要：
An optical communication apparatus includes an optical signal transmitting unit to output an optical signal; an optical signal receiving unit to receive an optical signal; a retro-reflector to retro-reflect the received optical signal in a direction opposite to an incident angle of the received optical signal; and a control unit to direct the retro-reflector to receive the optical signal and to retro-reflect a response signal, which includes the received optical signal and data to be transmitted, in response to the received optical signal.
