In an optical space communication apparatus, a first electrical signal is converted into a first optical signal, and the first optical signal is transmitted to a partner apparatus in the form of a first light beam. A second light beam transmitted from the partner apparatus is received to thereby detect a second optical signal by a photodetector of the optical space communication apparatus. The second optical signal is converted into a second electrical signal. A transmission direction of the first light beam and reception direction of the second light beam are changed in a direction to maximize an intensity of the second electrical signal obtained by converting the second optical signal detected by the photodetector. <IMAGE> |
