摘要

This article established the models of detection that groups of scattering particles flux with no relationship. According to the MIE scattering theory under the generalized, we derived the scattering light intensity of a single aerosol particle scattering of Gaussian beam and the luminous flux of ahead scattering formula. On the basic of the single particle scattering, we developed the scattering luminous flux formula of the groups of scattering particles flux, obtained the total population prior to the scattering luminous flux.Carried out using MATLAB editor and numerical calculation. The single particle flux and mass scattering curve with the off-axis distance was be simulated. As the results shows that the different scattering angle, the detector receives the flux is different; in the same axial distance, the luminous flux decreased quickly as the distance to the axiom increased. At the same time, the luminous flux affected the waist radius largely. Waist radius of the smaller, the smaller flux. It affected the luminous flux receiving when the groups of particles in different positions.
