热控涂层光学性能退化模型研究

Degradation model of the optical properties of the thermal control coatings

在实验研究成果的基础上,给出了热控涂层在空间辐照作用下的退化模型,接着用渐变折射率的概念对复折射率材料热控涂层的光学性能进行了分析,得到了退化前后热控涂层光学性能变化的表达式,最后对热控涂层光学性能退化模型的应用进行了探讨.

On the basis of experimental results,the degradation model of the optical properties of thermal control coatings due to space environment interaction are proposed. The optical properties of thermal control coatings prepared by complex refractive index materials are analyzed by using the concept of graded index,and the expressions of the changed optical properties of the coatings are given. Applications of the degradation model are also discussed.
