摘要
首先研究一点光源发出的某条光线经反射面上的点反射 ,建立了测试屏上的光点计算公式 .其次 ,采取使面积相等的技巧 ,将点光源的光线均匀离散化 ,并计算被反射的光线在反射点处的光强度 ,最后用计算机进行模拟求解 ,得到了线光源长度应为 4mm 。
First, in studying the reflection of a point light source by a point on the reflective surface, the calculating formula of the bright point on the test screen is established. Second, taking a technique, we scatter equally the beam of a point light source. Besides, the light intensity is calculated. Last, by the technology of computer-simulation, we obtain the conclusion that the length of the linear headlight source is 4 mm and draw the bright area.
