| 摘 要： | 基于DMD的红外场景仿真系统投影光路是仿真系统的关键组成部分。设计了一种准直投影光学系统，利用不同材料热性能互补的无热化光学设计方法，得到系统的初始结构，将某一面设计为二元面，降低了系统像差，提高了光学传递性能，达到系统的消热差设计。投影光路采用折射式结构，工作在8～12 m长波红外波段，焦距为113 mm，半视场角为4.5，F数为1.3。利用ZEMAX软件对光学系统进行了优化，满足了仿真系统的使用要求。

| Abstract: | Projection optical system is the key component of the infrared scene simulation system based on DMD. The projection optical collimating system was designed. The initial structure of the system was obtained by use of athermal optical design method for the complementary of different thermal properties. The one side was designed to the dual surfaces, the aberration was reducing, and the optical transmission properties was improved, system athermalized designs was achieved. The refractive structure was used by projection light path, working in 8-12 m long-wave infrared band, with focal length of 113 mm, half-field angle of 4.5 and F number of 1.3. Optical system using the software ZEMAX was optimized to meet the requirements for use of the simulation system. |
