Abstract

With the rapid development of microelectronics, nanotechnology and integrated design concept, the trend of satellite miniaturization is becoming more and more obvious, and the high resolution of small satellites is enhanced, and the capability of remote sensing is the forward position to promote space exploration and technological innovation. For the telephoto optical system, the influence of the spatial thermal environment changes and the change of the gravity field before and after the launch will change the focal length of the optical system, resulting in blurred image, so the need for focusing the focus parts to focus. According to the overall technical requirements of the satellite, a small-scale super-resolution spatial camera system based on the traditional Cass-grain optical system is designed. The modal, sinusoidal vibration and random vibration of the system are simulated by mechanical simulation software. The results shows that the mechanical properties of the system are good. The load has been successfully launched and a good image effect has been achieved.
