[0002] With the development of photoelectric technology towards large field of view multi-target detector, new requirements are put forward for laser pointing technology, which requires the photoelectric system to be able to irradiate and indicate multiple discovered targets simultaneously. The fast mirror, i.e. the fast reflecting mirror, is an essential part for accurately controlling the direction of the light beam. Therefore, the method of using multiple lasers and cooperating with multiple fast reflecting mirrors to accurately modulate the laser pointing has been widely applied.

[0003] According to the use requirements of multi-target photoelectric imaging detection indicators, the corresponding laser beams need to be accurately pointed to each target by controlling multiple fast mirror drives. In order to ensure the accurate correspondence between the laser light path pointing and the photoelectric detector imaging target surface, it is necessary to first ensure that the laser pointing coordinate system and the photoelectric imaging coordinate system are completely parallel in the three axis directions.
