摘要

A large aperture space telescope with a passive structure with high stiffness and thermal stability can maintain a good image quality in a large span of disturbance. However, for the proposed more stringent requirements, it is beneficial to add active optics to the conventional design. In these telescopes, the off-axis design provides more design variables than the coaxis system and also provides greater adjusting ability for the active optics. We introduce an active optics system prototype deployed on an off-axis space telescope working at low Earth orbit. By adjusting the low-order aberrations of the primary mirror shape and adjusting the positions and attitudes of certain mirrors and the focal plane, the optical system's image quality corrupted by gravity discharge and temperature variation is increased to the undegraded level in the average sense in the full field of view.
