介绍了长波红外消热差系统的种类,分析了温度对光学元件的影响,并列出光学参量随温度变化的公式。总结了红外消热差系统的设计原理,解出消热差消色差条件方程组并设计了一个工作波段为8~12 um,f=25 mm,F数1.2,配384×288,像元大小25 um非制冷探测器的系统。结果表明,系统结构简单,在-40℃~80℃温度范围内系统调制传递函数,均方根弥散斑直径变化均很小,符合红外消热差系统的条件。

This paper introduced the forms of athermal LWIR lens, and analysed the effects of optical elements when temperature changed. The equations of optical parameters shift with temperature were surmerised. Three simultaneous equations were solved to derive an achromatic and athermal system, whose focal length was 25 mm, f/number was 1.2. This system was compatible with uncooled focal plane array which has a format of 384×288 and the pixel pitch of 25 um. It can adapt a temperature range of -40℃~+80℃, and the properties were steady and extraordinary.
