Abstract

Abstract

The baffle is an important component of the space optical remote sensor, which is the main way to weaken the stray light from the out-of-field radiation source, and the imaging quality of the space optical remote sensor is dependent on the baffle's performance. In this paper, a large size baffle layout will be designed to meet the off-axis Wetherell TMA optical system. The baffle is made of carbon fiber reinforced polymer(CFRP). The FEM analysis, stray light analysis, mechanical vibration test and optical system MTF test are used to verify the usage requirement in aerospace. Results show that the MTF of the optical remote sensor can reach up to 0.2 in each field of view. It is indicated that the baffle has stable structure and good reliability and can meet the requirements of space applications.
