积分球光能均匀性的Monte Carlo模拟

为研究某工程应用的面光源入射积分球光能分布的均匀性，本文采用Monte Carlo法，进行大量光子的追迹，把积分球水平的划分为五个面积相等的环带；用Matlab编程，对各环带光能分布进行计算机模拟，验证了积分球光能分布的均匀性，可为积分球工程应用提供指导。

Simulation of the Light Energy Uniformity of Integrating Sphere Based on Monte Carlo Method

In order to study the light energy distribution uniformity of the engineering application integrating sphere which with the lamp-house incident,In this paper,with Monte Carlo method,tracking the large number of photons that incident into the integrating sphere,the integrating sphere is level divided into five zone which area is equal,With matlab program,the light energy distribution of each zone is simulated with computer,the simulation results show that the light energy distribution uniformity of integrating sphere,this simulation can be provide guidance for the engineering application of the integrating sphere.
