title = "Image quality degradation of high-resolution optical system caused by disturbance of satellite platform",
abstract = "During satellite moving on orbit, effect of disturbance of satellite platform motion on optical system cannot be neglected. The influence on image quality of high-resolution optical system caused by satellite platform motion was analyzed in this paper. First, as linear, sinusoidal and random motion are three kinds of fundamental motion mode of satellite platform, the effects of the disturbance of linear, sinusoidal and random motion on Modulation Transfer Function (MTF) of optical system were simulated respectively. Second, based on the simulation results, conclusion that the Modulation Transfer Function (MTF) was degraded in various degrees under different modes of motion disturbance was obtained. To improve the axis stability of optical system for a high-resolution image, a coupler was researched and installed between the satellite platform and the optical imaging system to attenuate the disturbance from the satellite platform, and adaptive optics correction was adopted to correct the residual disturbance effect in real-time. By combining the coupler and adaptive optics correction, the high-resolution imaging was guaranteed effectively.",
