Abstract：To improve the detection performance of laser light screen ,through the establishment of detection sensitivity model of laser light screen ,its detection performance was analyzed in this paper .The infrared laser was used to construct light screens emit‐ting light ,the relationship between detection screen area and the number of line lasers was given .According to the definition of de‐tection sensitivity ,combined with the working principle of laser light screen ,the detection sensitivity model was set up ,the light en‐ergy distribution on detection screens were introduced ,the influencing factors of laser light screens detection performance was ana‐lyzed .Through simulation results ,the laser light intensity and the visible LED light intensity was compared ,indicating the laser screen target detection sensitivity was proportional to the power of the lasers .Experiment showed the laser light screen had better detection performance than traditional light screen with visible light LED as a light source .
