PURPOSE:To provide the optical axis alignment method for optical radio transmission equipment capable of easy alignment of the optical axis of an optical radio transmission equipment. CONSTITUTION:An optical radio transmission equipment 1 consists of a transmission equipment 2 which generates first transmission light for signal transmission and a reception equipment 3 which converts the light received by a photodetector PD 4 to an electric signal and outputs it as the output signal, and the reception equipment 3 puts reception level information of the reception signal detected by a level detector 13 on a pilot signal to transmit it to the transmission equipment 2. The transmission equipment 2 takes out reception level information from the received pilot signal and displays the reception level on a level monitor 6, and the optical axis of the transmission equipment 2 is adjusted, thus aligning the optical axis. |
