| 摘 要： | 光学观测瞄准是大中型轰炸机主要的对地攻击瞄准方式,其光学系统一般采用望远式光学系统,这就要求光学系统能满足可见光和近红外光两个光谱波段。根据国内大中型轰炸机光学观测瞄准系统的主要缺陷,结合光学观测瞄准的实际,探讨了基于二元光学的光学观测系统的组成结构和瞄准原理,分析了可见光波段混合目镜的光学性能、谐衍射物镜的衍射效率以及近红外光波段光学系统的像质,推导了横偏棱镜调平误差引起的瞄准误差的数学表达式,并对设计的合理性进行了验证。

| Abstract: | Optical observation sight is a dominating air-ground attack method to a large or medium bomber,which its optical systems are usually chosen telescope.The telescope should demand two bands spectrum of visible light and near infrared.According to the optical observation aiming practice and its main limitation of a large or medium bomber,the configuration and the aiming principle were probed into based on binary optics.The optics performance of hybrid ocular in visible light,the diffractive efficiency of harmonic diffractive object lens and the optics system imaging quality in near infrared were analyzed.The mathematical expressions of aiming error caused by parallelism regulation error of transverse prism were deduced.The rationality of optics system design is testified. |
