Abstract

PURPOSE:To realize the optical transmission while the directions change relatively and without lowering the transmission efficiency by detecting the arrival direction of the light from the 2nd station via the direction sensor of the 1st station and then turning the directivity of the 1st station toward the 2nd station based on the detected direction. CONSTITUTION:Stations 1 and 2 are installed for the optical communication. And in case station 2 tracks light 3 emitted from station 1, the arrival direction is detected for light 3 via the direction sensor provided to station 2. The direction sensor is formed with several units of photo detectors 5 distributed at the circumference of disk 4, and thus the arrival direction of light 3 can be detected by the difference of the output among detectors 5. Then based on the information detected by the direction sensor, the directional characteristics of the sensor of the self-station is altered to the direction of light 3 sent from station 1.
