论述了目标仿真机构的用途、仿真的光学原理以及实现原理的光学系统。对其中的两个光学问题的研究作了详细地论述 ,即干扰光路 2倍于目标光路的视场角以及如何由摆镜的摆动实现。由于析光镜与光轴成 45°角 ,使像点在子午方向被拉长约为弧矢方向的 10倍。为了减少子午像差 ,将两块析光镜作成略带楔角的楔形镜。结果表明 ,由于该机构的尾焰、尾喷管用的是同一条光路 ,所以使结构大为简化 ,这对降低转动惯量非常有利 ;由于有干扰弹仿真 ,使机构的功能得到了扩大 Discusses the purpose of the simulation agency, simulation of the optical principle and the principle of the optical system. Two of the optical problems are discussed in detail, that is, interfering with the optical path of the target 2 times the angle of view and how to swing the pendulum to achieve. As the mirror and the optical axis into a 45 ° angle, so that the image point is stretched in the meridional direction about 10 times the sagittal direction. In order to reduce the meridional aberration, the two pieces of light microscope as wedge slightly wedge mirror. The results show that the structure is greatly simplified due to the same light path used by the tail flame and the tail pipe of the mechanism, which is very advantageous for reducing the moment of inertia; the function of the mechanism is enlarged due to the simulation of the bombs
