Automatic measuring system of alignment error based on laser collimator technique

YUAN Jiang,QIU Zi-xue,SHAO jian-xin ( School of Mechanical Engineering, Nantong University, Nantong 226007, China)  
The measuring Principle of alignment error based on laser collimator technique is introduced in this paper. The laser structure, the signal processing circuits and the data acquisition are proposed in detail. Based on two measuring and two calibration methods, the designed software has characters of high speed and can be applied to many alignment measuring instruments.
