Problems solved by technology

The reflector is adjusted from the initial attitude to the target attitude to realize the deflection within a small angle, so that the light beam reaches the receiving end. However, in practice, it still takes a long time for the receiving end to capture the light beam emitted by the sending end, and the rapid establishment of the communication link is an urgent problem. solve

Abstract

The invention discloses a path optimization method for rapid search by using a reflector. The path optimization method is specifically implemented according to the following steps: step 1, establishing a spherical coordinate system coordinate, and regarding a reflector surface as rotation in a spherical coordinate system; step 2, establishing a corresponding relation between the light spot miss distance and the rotation angle of the reflector, and controlling the rotation of the angle of the reflector by using a motor; according to a control loop of the two-dimensional rotating reflector module at a receiving end, establishing a relationship between the corresponding light spot miss distance and the rotating angle of the reflector; and step 3, performing optimization according to the method in the step 1, performing control driving according to the corresponding relation between the miss distance of the light spots on the reflector and the rotation angle of the reflector in the step 2, completing rapid search by using the reflector, and improving the link establishment speed of the wireless laser communication system. According to the method, the reflector can be deflected within a small angle, so that the laser beam can reach the field of view of the receiving end, and the establishment speed of a communication link is increased.

Description

technical field [0001] The invention belongs to the technical field of wireless laser communication, and in particular relates to a path optimization method for fast search by using a mirror. Background technique [0002] Wireless laser communication is point-to-point communication, the divergence angle of the beam is very small, and communication can only be realized after precise alignment. The establishment of a laser beam capture, alignment and tracking system can ensure long-term stability and effectiveness of the link, and the rapid establishment of a communication link is a prerequisite for wireless laser communication. [0003] Nowadays, in the wireless laser communication system, the research on erecting the mirror module on the UAV as a relay has been carried out successively. When the laser light exits from the sending end, it first reaches the mirror surface, and then the transmission direction of the laser light changes due to the reflection of the mirror, and ...
