  • There are some shortcomings in aiming correction before the artillery leaves the factory, just like the low degree of automation, the low resolution and accuracy. Aiming at these problems, we design a novel laser micro angular deviation measurement and proofread aiming system. The system consists of position sensitive detector (PSD), collimating parallel laser tube and two-dimensional precision spin controller, and the micro angle offset of artillery bore can be acquired in real-time using the photoelectric conversion and signal processing technology. The traditional proofread aiming method can be improved effectively using relatively simple means to complete the high precision measurement. Experimental test results show that the system can detect the micro angle deviation with the barrel elevation range of 0°~70° in the whole course, and its resolution can reach 0.001°. It can be widely used to proofread aiming with different caliber artillery bore.
