Abstract

Abstract

In order to estimate the SiC mirror surface figure under the space zero-gravity environment, extracting zero-gravity surface figure of SiC mirror by orientation reversal under ground environment was studied. Firstly, the principle of extracting zero-gravity surface figure by orientation reversal is introduced. Secondly, the effect of orientation reversal on mirror surface figure is analysed by finite element analysis software. Then, according to the flow chart, mirror surface figure of 0° and 180° conditions are tested successively, and the zero-gravity surface figure is obtained by average two measurements. The data indicate that the RMS value of the ground zero-gravity surface figure of mirror is 12.3nm, which meets the design requirement. Last, data credibility is analysed and confirmed. The obtained results indicate the mirror surface figure in the zero-gravity environment of space, which has important significance for optical fabrication and alignment of mirror.
