| Abstract: | The supporting structure of the large-aperture primary mirror of the space camera is the key technology for the space camera. This paper presents the problem that the ball-hinge supporting structure of a certain type of primary mirror will lead to the astigmatism when the external condition varies. Based on the research on the ball-hinge supporting structure, a novel flexure supporting structure was developed and optimized with numerical analysis. Some environment experiments were conducted, and the results... |
