Abstract

When the detection area of light-screen becomes larger, the optical and optoelectronic properties of light-screen will be affected and weaken its detection sensitivity. To improve the detection sensitivity and performance under the large detection area light-screen, this paper analyzes and designs a new light-screen based on array emitting diode and array receiving detector, studies the optical and optoelectronic properties of array emitting diode and its distribution of light energy, sets up the optoelectronic properties calculation model from which the array emitting diode’s transmitting power and detection output signal, provides light energy distribution mathematical model. Through simulation calculation and contrast experiment, the results show that the detection performance of new design large detection area light-screen has improved obviously, and the calculation model of optical, optoelectronic properties and light energy distribution in detection screen area is correct and feasible..
