Distributed Measurement of Micro-vibration and Analysis of the Influence on Imaging Quality

Abstract

The micro-vibration environment of optical remote sensing satellites is one of the main factors affecting the quality of in-orbit imaging and has become a research hotspot in the field of remote sensing. In order to ensure the in-orbit imaging quality of the satellite, this paper analyzes the requirement of the imaging quality on the vibration isolation and suppression of the micro-vibration of the satellite, and adopts the method of measuring the angular displacement of the main optical elements to analyze the impact of the micro-vibration on the imaging quality, analyzes and verifies the impact of the turning on of a certain type of satellite control moment gyroscope (CMG) group on the camera transmission.
