PROBLEM TO BE SOLVED: To obtain free-space optical communication equipment that can be installed and adjusted in a short time. SOLUTION: The position, etc., of a self-device is accurately detected by providing this free-space optical communication equipment with a GPS device 37, communication equipment 38, a direction sensor 39 and an inclination sensor 40, and installation and adjustment work can be performed in a shorter time than in the conventional practice by transmitting light to the opposite device. Even when the device is deviated largely by external force, automatic tracking can be performed and the original communication state can be restored only with short disconnection. |
