Abstract Based on the particle laser scattering , the paper puts forward a smoke recognition system with multi2sensor 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.
Key words smoke recognition , Monte Carlo simulation , photon transmission , light scattering
