Abstract

Baffle, especially the baffle with vanes, is a key element for stray light suppression of an optical system. In order to get well performance of stray light suppression, the long baffles are needed for some optical systems, such as Reflective Cassegrain System. However, the volume of the long baffle, which is not adaptive to the uses in the space environment, is too large. Therefore, a method of which the deployable structure is adopted in the baffle of the optical system is advanced innovatively. And a self-deployable baffle with vanes, which is able to stay in contraction state until it is working and deploy into long baffle state as required rapidly, is designed. The novel baffle in this paper is able to ensure good performance of the baffle with vanes and solve the problem of the baffle used in the space environment. Then, the performance of the tape spring is computed.
