Design and Analysis of A TMA Telescope for Next Generation Earth Observation Satellite

摘要

Three mirror anastigmatic (TMA) telescope provides a better solution to meet the requirements of high resolution and wide swath, it has become one of candidate to be next generation observation payload for satellite. This article reports on design, analysis, assembly and implementation of a TMA telescope for next earth observation satellite. A straightforward approach is presented that integrated finite element method and Zernike polynomials fitting techniques is found to successfully predict optical performance. Furthermore, an optomechanical structure of TMA optical system was configured which is implemented to verify the present.
