ABSTRACT:
A wireless optical communication systems using two optical transceivers located at the opposite ends of an optical communication line. The optical communication system can be either two-element, when each of the said transceivers contains one optical transmitter (emitter) and one optical receiver, or it can be four-element, where each of the said transceivers contains two optical transmitters and two optical receivers. The output of each of the optical transmitters is a diverging beam of incoherent electromagnetic radiation arranged to have a cross sectional diameter which is larger than the cross sectional diameter of the respective optical receiver at that point on the communication line at which the respective optical receiver is situated. The invention reduces the probability of communication failure, higher noise resistance, and lowers operation and production costs.
