Paper Abstract

This paper proposes a kind of ballistic range spatial benchmark control system, which is based on the Position Sensitive Detector (PSD) and multidimensional stepper motor console. The method— how to control a stepper motor automatic implement space benchmark according to the position of light spot on the PSD is also given. Besides, the camera stations in ballistic range have been calibrated by the spatial benchmark devices. Experimental results show that PSD-based spatial benchmark system can effectively eliminate errors caused by the artificial operation between different stations, and its spatial precision is superior to 0.1mm.
