The invention relates to a rotating mirror system for automatically changing a prism. The rotating mirror system comprises a rotating mirror device, a loading and unloading device, and a rotating mirror library device, wherein the loading and unloading device is placed between a rotating mirror assembly and a rotating mirror library and is slidably mounted on the working table surface through a first linear motor; in the movement direction of the loading and unloading device, a plurality of rotating mirror assemblies and a plurality of rotating mirror libraries are arranged on the two sides ofa movement trail of the loading and unloading device; the loading and unloading device comprises a movement column body fixedly mounted on a first linear motor dynamic sub-seat, a top plate fixedly mounted at the top end of the movement column body, a second linear motor fixedly mounted on the top plate, and a mirror body clamping assembly fixedly mounted on second linear motor dynamic sub-seat;and the mirror body clamping assembly clamps a mirror body assembly and moves to the placed position of the mirror body assembly in the rotating mirror device or the rotating mirror library device through the second linear motor. Compared with the prior art, the rotating mirror system for automatically changing the prism has the advantages of convenient lens replacement, high degree of automation,high scanning accuracy, no scanning blind area, and no extrusion for mirror body mounting.
Description
technical field [0001] The invention belongs to the field of optical transmission systems, in particular to a rotating mirror system for automatically changing prisms. Background technique [0002] With the continuous development of space optical system in imaging and detection, the requirements for the performance and function of the rotating prism scanning mechanism are getting higher and higher. When the double prism is in the working state of scanning and tracking, there is a scanning blind area and the scanning area is small. It is necessary to use multiple prisms to work at the same time to eliminate the blind area and expand the scanning range. Under different working requirements and working environments, it is necessary to realize the functions of independent combination and replacement of lenses. Prior technology (patents such as Li Anhu, application number 201711381976.8, application date December 20, 2017, patent name "rotary double prism integrated mechanism dr...
