The Research On Measuring System About Directing Line Of White Sight With High Resolution

The variational momentum of directing line is the primary factor of effecting the accuracy of weapon firing and one of the essential testing project after it's firing,so it's necessary to design a system to measure it.The variational momentum of directing line is the offset of directing line on the reticule and one of the standard to evaluate properties of stability. A high accuracy system to measure the variational momentum of directing is designed in the case of assuring the same position of sight device after firing.The paper described the composition and principle of the system and designed mechanical structure and optical system, and micromotion reading subdivision device is improved. Micromotion subdivision equipment is designed to measure image point position by turning plate glass in the base of micromotion subdivision to zero method. The base and gripper are designed specially to combined with measuring instrument. The system has application value by accurate reliable, high stability and convenient and fast when it read. Dismounting and maintenance are simple.
