摘要
建立了用于温度效应分析的光学系统热模型,提出了一种光学机械综合优化的被动补偿方法,该方法将光学系统中光学元件和相关机械零件温度特性统一参与光学系统优化设计,保证在较大的温度范围内都可以有很好的成像质量。设计实例表明,采用这个方法可以在不增加光学和机械结构复杂度的情况下得到良好的光机被动无热化效果。
A themal model for themal effect analysis of optical system is established, and an optical mechanical passive compensation method is proposed. Optimization design includes the thermal characteristics of optical and mechanical parts. This method can get fine imaging quality of the optical system in a wide temperature range. As shown by the example, optical and mechanical athermal compensation is obtained without adding the complexity of optical and mechanical structures.
