To realize real-time and precise position and pose detection of a moving ta rget,a solution to build two-dimensional scanning light field is proposed.Two sets of identica l but independent single axis scanning systems,which are vertically placed,make up the launch syst em and realize the scanning of X and Y di rections.According to the received signal,the moving targets can get relative position and pose in the launch system coordinate.It simplifies th e subsequent signal processing procedure and reduces the amount of calculation.The analysis results show that the uniformity of line laser beam is more than 90%,the energy utilization rate is m ore than 70%, and the distortion is less than 0.5%.A rectangular light field with a scanning optical angle of ±20°×±20° is built by two sets of single axis scanning systems.The sys tem with high energy utilization rate and good stability is helpful for the prac tical applications.
