Abstract

The present invention relates to the technical field of remote sensing scanning mirrors, in particular to a sliding installation device with a compensation mechanism for remote sensing scanning mirrors. The present invention sets precision compensating components on both the first rotating mechanism and the second rotating mechanism. In this way, not only The rapid angle adjustment of the scanning mirror can be realized, and the high-precision compensation of the angle can be realized, and the precision compensation component of the present invention can control the first rotation mechanism and the second rotation mechanism according to the satellite attitude deviation information corresponding to the remote sensing scanning mirror. The angle after the rotation of the mechanism is precisely compensated, and the angle range compensated by the precision compensation component is -5° to +5°, ensuring image quality. The angle compensation driving mechanism of the present invention can realize high-precision control, and real-time detection feedback control , the shape and size of the compensation ring groove can be designed according to the required accuracy and other conditions, so as to realize the control required by different accuracy or angle compensation, and improve the accuracy of angle control during the sliding process.

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...
