An Improved Barycenter Method Used in Light-trap Center Acquiring

This paper introduces laser ambulator simply,on the basis of analysis the principle and classes of grating sensor,in view of the problem that ambulator requires high precision when surveying the high voltage cable,a scheme of using grating sensor in laser ambulator is proposed.Two diffraction gratings sensors in the laser ambulator platform design are installed,which separately output elevation angle and the agimuth angle,and the subdivision circuit of grating sensor is designed using subdivision algorithm,increasing the measurement precision greatly.
