摘要
对太空反射镜在空间环境作用下所产生的带电粒子和在辐照、分子污染、热效应及空间粉尘撞击等效应的研究现状进行了评述,阐明了深入开展空间环境下反射镜损伤机理及性能演化规律的必要性。研究结果表明,空间环境因素会对光学反射镜造成不可忽视的损伤,包括出现反射率下降、辐照起泡、辐照剂量效应、面形改变等现象。
The research actuality of space environment effects on reflection mirror such as charged particle radiation, contamination is reviewed. Under the space environment the research necessity of damage mechanism and performance evolution of reflection mirror is illuminated. The research results show that the damage effects induced by space environment factors can not be negligible, which include transmittance decrease, radiation bubble, radiation fluence effect and surface shape change.
