军事上高的速高比(V/H)要求推动了研制适用于很高 V/H 值的分离孔径扫描器,该类型扫描系统可以进行战术侦查、空中监视以及特殊任务的执行,多数军用红外扫描系统现都采用分离孔径式设计。介绍了分离孔径式光学系统设计中的主要技术参数确定、布局形式和结构特点,并就工程实现过程中容易出现鬼像、冷反射及光路合像等主要问题展开讨论.
The military high speed / height ratio (V / H) requirement has led to the development of split aperture scanners for very high V / H, which can be used for tactical detection, aerial surveillance and special mission execution. Most military infrared The scanning system now uses a split aperture design. The main technical parameters, layout and structural features in the design of separation aperture optical system are introduced. The main problems such as ghosting, cold reflection and co - registration of light path are easily discussed in the process of project implementation.
