| Abstract: | The shape and distribution of inner stress of optical elements will vary in the space circumstances or other special operation conditions,which will influence its optical characteristic dramatically.In this paper,the influence of the inertial load aroused by the large acceleration has been performed;the effects of the varying circumstance temperature on the optical element have been studied preliminarily by use of finite element method. |
