反坦克飞机导弹光学瞄准设备这种瞄准设备有一个电磁辐射探测器、主透镜系统和后透镜系统，每个透镜系统均有调制设备，在透镜和探测器之间有一个由两部分组成的屏蔽，屏蔽的孔由在屏蔽两瓣内部分重叠的窝穴构成。两个瓣在共有的固定轴上是倾斜的，这样就确定了开孔的位置... Anti-Tank Aircraft Missile Optical Aiming Equipment This targeting equipment has an electromagnetic radiation detector, a main lens system and a back lens system, each with a modulation device, a two-part shield between the lens and the detector The shielded holes are made up of partially overlapping pockets within the shielded two lobes. The two flaps are tilted on a common fixed axis, thus determining the location of the opening.
