| 摘 要： | 探讨了温度变化导致光学系统像面离焦的原理,介绍了目前国内外典型的消热方法,分析了光学系统被动式无热补偿的优势,推导了实现热补偿需要满足的无热化方程组.提出一种光学和机械相结合的无热补偿方法,采取该方案补偿后的光学镜头在环境温度发生变化时像面与传递函数保持相对稳定,即光学系统基本实现无热化,这对红外镜头的无热化设计具有重...

| Abstract: | The principle which can cause the defocus of the image surface is discussed.The domestic andforeign athermalisation methods are introduced,the advantages of passive athermal compensation of the opticalsystem are analyzed,athermal equations of thermal compensation are derived.An athermal compensation methodwhich combines the optics with the machinery is proposed.Using this method,the optical lens and the transferfunction can keep relative stability,when the environment temperature changes,that is,the atherma... |
