Abstract
An FSO communication system includes a laser, an optical detector and a first optical adjustment module and a controller. The laser is configured to emit an optical signal. The optical detector is configured to receive an optical signal from the first optical adjustment module. The controller is configured to obtain an optical power of an optical signal received by the optical detector; and generate a control command based on the optical power and transmit the control command. The first optical adjustment module is configured to: receive the control command and the optical signal emitted by the laser; adjust, in response to the control command, the optical signal emitted by the laser to cause the optical power of the optical signal received by the optical detector to be in a preset reasonable range; and transmit the adjusted optical signal to the optical detector.
