The invention relates to the technical field of remote sensing scanning mirrors and in particular to a sliding type installation device used for a remote sensing scanning mirror and provided with a compensation mechanism. Precise compensation components are arranged on a first rotating mechanism and a second rotating mechanism, in this way, quick angle adjustment of the scanning mirror can be achieved, and high-precision compensation of angles can also be achieved; and besides, the precision compensation components can carry out precise compensation on angles after rotation of the first rotating mechanism and the second rotating mechanism according to satellite attitude deviation information corresponding to the remote sensing scanning mirror, the compensation angle of the precision compensation components ranges from -5 degrees to +5 degrees, and image quality is ensured. An angle compensation driving mechanism can achieve high-precision control, and control is detected and fed back in real time; the shape and dimension of a compensation annular groove can be designed according to needed precision and other conditions, control needed by different degrees of precision and angle compensation can be achieved, and the precision of angle control in the sliding process can be improved.
Description
technical field [0001] The invention relates to the technical field of remote sensing scanning mirrors, in particular to a sliding mounting device with a compensation mechanism for remote sensing scanning mirrors. Background technique [0002] At present, for remote sensing scanning mirrors, when observing the earth with remote sensing satellites, the movement of the scanning mirrors has an important relationship and influence with the attitude information of the satellites, thus affecting the image quality. Therefore, when using the scanning mirror to scan, the satellite attitude deviation information needs to be taken into consideration. As for satellite attitude deviation information, due to its high precision requirements, the installation structure of ordinary remote sensing scanning mirrors is generally only realized by using rotating parts and sliding parts. This method and structure are difficult to meet high-precision sliding and angle adjustment. It is difficult t...
