摘要	Space cameras are used for the detection and observation of a faint target in space. Image contrast degrades once stray light arrives at the detector such that the camera can sometimes fail. Optical systems with wide fields of view are particular sensitive to the stray light. Therefore, this paper analyzes the source of stray light for a space camera with a large field of view and summarizes suppression measurements through the research of stray radiation energy transmission theory. To satisfy the required size indicators, a vertical optical axis and the inclined hood are designed within a limited size so that the light shading structure can be discontinued. Results from a Tracepro simulation show that baffle with lean vane leads to better suppression of stray light, and that the point source transmittance out of the rejection angles of the system is at 10-7. The system can detect at least 6.5M stars. The suppression technique is proven to be effective and can be used as a reference for further optimization and design. 2019, China Science Publishing & Media LTD. All right reserved.
