Abstract
In an optical atmospheric communication apparatus for transmitting desired information via an optical beam circulating in the atmosphere, the position of a transmitting object can be easily detected and thus the projecting position of an optical beam can be corrected, even in the case where the optical beam coming from the transmission object cannot be received. The projecting position of the optical beam is displaced within a prescribed range, and the light receiving area of the optical beam reflected at a corner cube reflector is detected in order that the projecting position of the optical beam is corrected based on the centroidal position of the light receiving area.
