Application and analysis of mirror discrete support technology in optical remote sensor

Discrete support technology has been widely used in the mirror support of space optical remote sensor due to its high lightweight and good environmental adaptability. In this paper, a six point discrete structure is designed to meet the high force and thermal stability requirements of a lightweight mirror with a diameter of Φ550mm in a high-resolution space camera. Through the analysis of the mirror stiffness and the adaptability under various environmental effects such as gravity, temperature, shrinkage of glue spots and overload, the rationality of the structural design is verified, and the indicators meet the application requirements of space optical remote sensor.
