Research on Dimensional-separation Coding for Laser Direction Detection

LANG Wen-jie (School of Information and Communication Engineering,The North University of China,Taiyuan 030051,China)  
In a big field of view for realizing on any direction of laser detection,simultaneously guaranteed that the structure stable,responds,the low cost and so on,dimensional-separation mask encoding method was designed.The system of laser direction detection uses six even-window detectors, and was constituted in the horizontal plane the dimensional-separation mask way.Using the mask and the detection angle,it might calculate the field of view of the dimensional-separation encoding,thus realized the laser direction.According to the experiment,the laser direction can be calculated by the coding method with six detectors,and the Accuracy of angle can reach 30°.The experiment of laser with incline incidence to the detectors knows,under worst-case laser incline incidence conditions response voltage was more than 40 mV,so the system field of view is the cone zone form 18°to 162°.
