Most of wireless laser communication links on the market carry out early-stage alignment work in a manual adjustment mode, infrared light is difficult to observe by naked eyes of human beings, the target position irradiated by laser can be observed only by other technical means, and the alignment difficulty is high. A common method is to adopt auxiliary visible laser to align infrared laser, and the alignment modes of the auxiliary visible laser are generally divided into two modes, one mode is to directly transmit the infrared laser and the auxiliary visible laser through a laser collimator at the same time, but aiming at different application scenes and communication requirements, the light transmittance of the collimator adopted by the infrared laser to the visible laser is low, so that the auxiliary laser cannot irradiate the position where the infrared laser can irradiate; the other method is to provide reference for the infrared laser through the auxiliary alignment laser and find the actual position of the infrared laser according to the position of the auxiliary alignment laser, and the method requires that the auxiliary alignment laser and the infrared laser at the output end keep certain parallelism, which needs a complex mechanical structure to realize.
