AbstractTo investigate the flywheel micro vibration effect on the camera imaging quality, the method of integrated modeling and ray tracing was used. The integrated modeling is to set up disturbance model of the micro vibration of the flywheel, the finite element model of the satellite and the camera. By the transient response analysis, the displacement of all the mirror with the time under the action of force or moment in 6 directions respectively is obtained. The ray tracing is based on reflection mirror displacement and the incident light, according to the refraction law to calculate the location and direction of the ray, and the angle between the ray and the optical axis. Then, the spot coordinates and displacements of the image plane are obtained, and the Modulation Transfer Function (MTF) of the system is calculated by using the statistical moment of motion. The results show that the response period has nothing to do with the excitation period; the length of excitation time and sampling time affect the MTF; different direction vibration causes the change of MTF of different sizes, indicating the size of angular and linear vibrations on MTF; and different direction effect on MTF is similar between with the original optical system and with only vibration, where MTF attenuation reaches maximum when My, Mz is loaded respectively, up to about 0.1. The research method is simple and fast, and the relationship between the micro vibration and the MTF is obtained, which provides reference for the system design and vibration isolation. 2016, Science Press.
