摘要
依据光辐射理论,采用系统损伤分析法,建立了一套空间光学系统光路辐射损伤分析模型,并对可能在空间使用的全反射、折反射、全折射光学系统的辐射损伤进行了计算比较,给出了光谱损伤函数和防护判据条件.设计中应尽量选用全反射光学系统,对于长镜简的折反射系统可以不用特别考虑防护问题,对于短镜筒的折反射系统,此时的防护要依据判据考虑是否选用防辐射窗口玻璃设计.对于必须采用到全折射式结构的空间光学系统,它的防护设计也应依据上述判据进行分析.
The matrix analysis modei can be used for radiation damage analysis of a holophote, refraction and reflection or full refraction optical system used in space, and that the effect of a space radiation on the system should be considered carefully and protection should be taken into consideration in design of the refraction and reflection or full refraction system. The holophote optical system should be used in the design of space 6ptics system if possible. When a refraction and reflection or full refraction system must be used, the analysis of ad-vantages and disadvantages should be conducted. A criterion that would be considered in the design-of the sys-tem radiation protection with window glass is ratio T'/T'.
