Abstract
A variable optical transmitter includes a light emitting element which prcts a very compact beam of light. The transmitter is constructed to be adjustable so that the light beam may be transmitted at any desired azimuth angle around a vertical axis. By directing the light beam vertically toward a fixed reflector, projection of the beam in any desired horizontal direction may be achieved by a very slight deflection of the beam source from the vertical. The apparatus may also include a receiving portion which will detect the direction of receipt of an incoming light beam. The device may thus be used to transmit a light beam precisely in the direction from which a signal was received.
