本文介绍了一种新研制的非接触式三维弹头痕迹检测系统的原理、结构、控制以及实验结果。
In this paper, We introduce the principle, structure, control and experiment result of a new non-contact measuring system for 3d bullet marks.
进膛痕迹、线膛痕迹、坡膛痕迹、拔弹痕迹是弹头经枪械运动循环后，在弹头上形成的四种主要的弹头痕迹。
Chamber-loading trace, rifling trace, chamber throat trace and bullet pulling brace are the four major bullet traces which formed on the bullet after its movement circulation.
该系统采用了一种新型的微恒力位移传感器，该传感器具有测量力小且恒定的特点，因此，可以实现对弹头表面痕迹的无损测量。
A new micro constant force displacement sensor with micro and constant measurement force is introduced. It can realize the measurement of bullet marks without damage on the surface of sample bullets.
