Abstract:

In order to provide necessary data for data preparation and the theoretical basis for the design of larger detection light-screen,a research is conducted on the detection light-screen's energy and performance.This paper first introduces the principles of the light-screen target,and then through the analysis of a single light-emitting diode builds a single light-emitting diode's mathematical model by approximation processing methods and using the mathematical algebra and superimposed light energy distribution within the light-screen;and finally analyzes the performance of the light-screen from light the characteristics of the light-screen,the characteristics of the target,and the characteristics of detection circuit.This study lays a theoretical foundation for the design of light-screen with higher precision.
