A novel design for laser orientation detection system

CHENG Yu-bao; LI Qing; LIU Shang-qian

Based on the analysis of interference stripes of equal thickness generated by the parallel laser on optical wedge,a new scheme for laser orientation detection system is presented.The mathematic model of the scheme is introduced in detail,and its realization is provided.The system is composed of six optical wedges for orientation detection and the corresponding detection circuits.The orientation and wavelength of the incident laser are determined by measuring the space between interference stripes on optical wedges.The experimental data are given,which indicate that the system has some advantages such as high location precision and fast response.
