초록

Freeform mirror with freeform is to concentrate sunlight, and reflects light. The light connecting freeform mirror to freeform mirror is processed by one image and displayed as a picture that people can see. This one picture is used to observe the planets of the universe and the earth from space. In order to obtain a picture of the tens of thousands km away, the performance of the freeform is very important. Performance of the mirror for observing the ground are having an effect on deformation for gravity. Deformation of reflector mirror is affected by position and thickness of mirror support. In this study, strain and stress of the reflector has been simulated by thickness of mirror support.

Abstract

Freeform mirror with freeform is to concentrate sunlight, and reflects light. The light connecting freeform mirror to freeform mirror is processed by one image and displayed as a picture that people can see. This one picture is used to observe the planets of the universe and the earth from space. In order to obtain a picture of the tens of thousands km away, the performance of the freeform is very important. Performance of the mirror for observing the ground are having an effect on deformation for gravity. Deformation of reflector mirror is affected by position and thickness of mirror support. In this study, strain and stress of the reflector has been simulated by thickness of mirror support.
