OPTICAL PATH CORRECTION CONTROLLER FOR OPTICAL SPATIAL COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an optical path correction controller for an optical spatial communication system that attains an asymmetrical constitution wherein the optical path correction controller is arranged on only one side of optical spatial communication in order to correct an optical axis deviation due to disturbance such as vibration and wind.

SOLUTION: The optical spatial communication system which performs bidirectional communication has the optical path correction controller 16 which is arranged adjacent to one optical fiber cord 22 and adjusts a propagation path of laser light so that the optical axis of the optical fiber cord 22 or the center axis of the laser light emitted from the optical fiber cord 22 is aligned with the center axis of laser light arriving from the other optical fiber cable 12.
