| 摘 要： | 建立了以圆柱反射取得面光源的模型，利用计算机对多变量的无穷级数进行求和计算，证明点光源发出的光经柱面反射到达另一端端口时，将形成一个光强分布均匀的面光源，分析了在不同精确度要求下均匀面光源与各参数之间的关系．

| Abstract: | The cylinder model for plane light source is established, the distribution of light on the port of the cylinder is studied. The calculated results show that the plane light source is almost even. With the change of cylinder parameter, the uniformity of plane light source is also changed. |
