The existing optical head layout scheme mostly adopts modularized layout, and has high decoupling degree but causes structural member redundancy, so that the optical head cannot be miniaturized. The traditional high-precision rough pointing mechanism mainly comprises a swinging mirror type, a theodolite type, a kude type, a periscope type and the like, can effectively meet the working requirements under respective scenes, and has the defects of single adaptation scene, insufficient compactness and the like.

Meanwhile, due to the defects of high mass center position of the optical head and the like, the traditional design method has poor mechanical resistance of all groups of components on the optical head, and the emission active section can generate larger dynamic response so as to cause out-of-tolerance product indexes.
