Design of Linear Light Source Composed of Light-Emitting Diode Array in Large Light-Screen Target

采用发光二极管阵列构造线了一种大尺度线光源,文中分析了发光二极管阵列光源能量在空间上的分布,用光照度计实测能量分布数据,以二维坐标给出了能量平面分布图.设计的线光源满足大靶面弹丸测速光幕靶的要求,文中给出了在光幕靶接收器件处阵列线光源光能量的计算公式,实验验证了分析的正确性.

Using light-emitting diode (LED) array, a larger scale linear light source was designed. The energy distribution of which was analyzed. Distribution data was measured with illuminance meter. Two dimensional energy plane distribution plots was given out. Linear light source designed meets the need of completely the large screen target used to measure the flying bullet velocity. The formula that computes the energy of light source on where the receiving sensor was mounted was given. The result was verified by experiment.
