Based on Monte-Carlo fundamentals,by matlab program,the performance of light power transformation by an integrating sphere with radius of 100mm and diffuse reflectance of 0.85 was simulated. 100000 photons were randomly sampled and traced.

• 运用Monte-Carlo法原理；用matlab软件编程；通过随机抽样；追迹了100000个光子；对一半径为100mm；漫反射率为0.；85的积分球的光功率波形变换特性进行了模拟。
