Thermal Effects for Optical System and Design of an Analysis Program

摘要: 研究温度对光学系统的影响，讨论无热设计方法。采用温度热膨胀系统和光线追迹分析温度变化对光学系统结构参数的影响及成像质量的变化。研究表明，温度对光学系统的影响是明显的，无热设计是可行的。温度的热效率不可忽视，利用热效应分析光学设计软件可对光学系统的热效应进行有效分析。

Abstract: To study the effects of the temperature variation on the optical system, and discuss the method of athermalisation, the effects were analyzed by using the coefficient of thermal expansion and with the method of ray tracing. The thermal effects is distinct, however athermalisation is feasible. The thermal effects can not be ignored and the analysis of the effects can be completed with the method presented.
