SYSTEM FOR CONTROLLING PARALLELISM OF LASER EMITTING OPTICAL AXIS AND TARGET TRACKING OPTICAL AXIS

摘要

A system for controlling parallelism of a laser emitting optical axis and a target tracking optical axis, comprising an optical axis parallelism measurement unit (10), a control unit (20), a target tracking optical axis correcting unit (30), and a laser emitting optical axis correcting unit (40). The optical axis parallelism measurement unit (10) is used for measuring the offset of the target tracking optical axis and the offset of the laser emitting optical axis. The control unit (20) is used for controlling the target tracking optical axis correcting unit (30) according to the offset of the target tracking optical axis and controlling the laser emitting optical axis correcting unit (40) according to the offset of the laser emitting optical axis. The included angle between the laser emitting optical axis and the target tracking optical axis can be measured by means of the optical axis parallelism measurement unit; when the included angle does not satisfy a requirement, the correcting unit is used for correction; therefore, the parallelism of the laser emitting optical axis and the target tracking optical axis can be ensured and the emitted laser is ensured to precisely hit the target.
