摘　　要：提出了一种基于粒子激光散射的多传感器阵列的烟雾识别系统 ,描述了用蒙特卡罗模拟烟雾粒子散射特性的一般方法 ,模拟并验证了在不同粒径、折射率和入射角情况下烟雾粒子散射光强的角分布情况 。Based on the particle laser scattering, the paper puts forward a smoke recognition system with multi sensor array. And then a Monte Carlo method is described to simulate the scattering characters of smoke particles. By changing the sizes, refractive index of the smoke particles and incident angles of light source, the simulation results fit well with the classical results derived from Mie scattering theory.
