Chen Shudan1,2 Wen Desheng1 Yang Wencai1,2 Wang Hong1(1.Xi'an Institute of Optics and Precision Mechanics,Chinese Academy of Sciences,Xi'an 710119;2.Graduate Student College of The Chinese Academy Sciences,Beijing 100039)  
A spacial transient optical signal location image process based on the high-speed Digital Signal Processor is designed.A term of location process system is introduced based on the imaging characteristics of spacial transient optical signal.For Improving processing speed,filtrating the background and weak noises by threshold segmentation,for improving system's accuracy,disposing the distortion and calculating the Centroid of target data at last.Experiment results show that processing speed and measurement accuracy of this method are high,and can satisfy the request of locating system.
