Abstract
A spatial optical communication system in which a plurality of transmitters and a plurality of receivers opposite to each of the plurality of transmitters perform an optical communication in parallel, in which the plurality of transmitters transmit optical signals of same or adjacent wavelengths to the receivers of each opposite location, and has an interference blocking unit which is disposed between the transmitter and the receiver and spatially blocks an optical signal that interferes with the receiver of a non-opposite location among optical signals transmitted from the transmitter to the receiver of an opposite location. As a result, it is possible to avoid interference with other optical communications with a reduced space and at low cost, without need to supply power.
