The Research On Testing Variational Momentum System Of The Zero Position For Gun Aiming Device

Testing variational momentum of the zero position is one of essential contents in designing and other nature experiments of optics aiming device, simultaneously it must inspect before the gun fire, directly affects the gun's accuracy.The variational momentum of the zero position is that the sighting line of object space changing quantity after the fire, is the quantitative evaluation target of the optic aiming device. Testing variational momentum system of the zero position can not destroy relative position between testing system and optical aiming device, precisely tests variational momentum of the zero position.This article introduced the composition and the working principle of testing variational momentum system of the zero position, and the reading subsystem was designed. Testing variational momentum system of the zero position is composed of the directional hand wheel, the pitching hand wheel, the objective lens, the collimator, the dividing board and the illumination. This system can measure more accurately and read the variational momentum of the zero position directly. It is very convenient. Therefore it has very good application value.
