The invention relates to a rotating mirror system for automatically changing prisms, comprising a rotating mirror device, a loading and unloading device and a rotating mirror library device, the loading and unloading device is placed between the rotating mirror assembly and the rotating mirror library, and is slidably installed on the On the working table; along the moving direction of the loading and unloading device, several rotating mirror assemblies and several rotating mirror magazines are arranged on both sides of the moving track of the loading and unloading device; the loading and unloading device includes a moving cylinder fixed on the first linear motor mover seat , the top plate fixed on the top of the moving cylinder, the second linear motor fixed on the top plate, and the mirror body clamping assembly fixed on the second linear motor mover seat; the mirror body clamping assembly clamps the mirror body assembly , and move to the placement position of the mirror body assembly in the rotating mirror device or the rotating mirror library device by the second linear motor. Compared with the prior art, the present invention has the advantages of convenient lens replacement, high degree of automation, high scanning precision, no scanning blind area, no extrusion of mirror body installation, and the like.
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...
