红外光学系统无热化设计的途径

介绍了目前国内常用的主动式无热化技术和国外已成功采用的被动式无热化技术的原理。根据国内的加工工艺水平,分别从3个角度:球面系统光学材料匹配;引入非球面;使用简单的机械辅助结构讨论了从国外引进被动式无热化技术的可能性。经实例设计和大量数据分析得出结论。另外还介绍了目前国内适用于热成像的红外光学材料。

Approach of athermalizing infrared optical systems

The active athermalizing technique used usually in our country and the passive athermalizing technique adopted successfully overseas are described. Considering domestic conditions, the possibility of introducing the passive athermalizing is discussed from three ways, matching optical material used in the system that is all composed of spherical surfaces, using an aspherical surface and using a simple mechanical framework. Furthermore, the conclusions are given by design of a example and analysis of a great deal of data. In addition, infrared optical material, which is suitable for thermal imaging in our country now, is described.
