(1)歼击机光学显示器中的垂直偏差歼击机光学显示器的任务是测量目标相对于我机的距离并构成一显示一个命中目标所必需的总修正角。测距的任务,可通过显示器中的光环直径(角值)和目标大小一致,即外基线法来完成。总修正角往往是以显示器中的一块反光镜二自由度转动,或者是两块单自由度反光镜分别转动来构成。然而,这两种方法,无论哪一种,在构成总修正角的过程中,在光学原理上都将产生一定的误差。一般,飞机在地面校靶时,总是把武器轴线和飞机机身轴线校平行。如果把飞机机身轴线称为OX轴,水平轴线称为OZ
(1) Vertical Deviation in Pursuit Optical Display The mission of the fighter optical display is to measure the distance of the target relative to my machine and to form a total correction angle necessary to display a hit target. Ranging tasks, through the monitor aura diameter (angle value) and the same target size, that is, external baseline method to complete. The total correction angle is often two degrees of freedom with a mirror in the display rotation, or two single-degree-of-freedom mirror were rotated to form. However, neither of these two methods will produce some errors in optics in the process of forming the total correction angle. In general, aircraft on the ground when the target is always aligned with the axis of the aircraft fuselage axis. If the aircraft fuselage axis is called the OX axis, the horizontal axis is called OZ
