摘要:
论述了利用衍射元件实现光学系统无热化的原理,并利用衍射光学元件特殊的消热差和色散特性,设计并研制了折衍混合无热化车载红外镜头,在仅使用一种红外材料的情况下完成了宽温度范围自调焦设计,且衍射面特征尺寸大,易于加工制作。系统工作波段为8~12 ?m,视场为36?×27?,焦距为19 mm,F/#为1.1。该镜头体积小,重量轻,结构简单,非常适于在汽车辅助驾驶系统应用。镜头的测试结果表明,镜头成像质量好,且能在-40~80℃温度范围内保持像面稳定,无需手动调焦。
Abstract:
The athermal principle of diffractive element in optical system is discussed,and a refractive-diffractive vehicular infrared lens is designed and fabricated based on the unique athermal and achromatic characteristics of the diffractive elements. The system, made from only one kind of infrared material, is with self-focusing at wide temperature range. The diffractive surface is with large feature size, which is beneficial to manufacture. The working waveband of the system is from 8 to 12 ?m, the focal length is 19 mm, the F/# is 1.1 and the field of view is 36?×27?. The lens, which has features of small size, light weight and compact structure, is suitable for the auto-auxiliary driving system. It is shown by actual testing that the image plane is stable in a range from -40℃ to 80℃ without manual focusing, and the imaging quality is satisfactory.
