【Abstract】 For improving the quality of laser spot image,a new collection system of laser spot image based on image sensor camera is designed. This paper introduces three ways to modify the error of image sensor collection. Giving the drive pulse of image sensor camera through its image sensor camera drive module,collecting original spots by image sensor camera which is YD-ZA724 IR,changing the analog signal which is amplified into differential signal through the signal processing module to eliminate the interference,convert the ads807 chips of supply sample module into digital signal,display the standard laser spot image in system computer by using optical 4F system,using CC-EP418 chips by control module to support the function for the modules above. Finally,the experiment proves its reliability and image transmission time.更多还原
