Abstract

When the laser passes through the haze atmosphere, the laser interacts with the haze particles and scatters. The scattered light will take away the energy of the laser beam. At the same time, the scattered light maps the physical characteristics of the haze particles, such as the particle size parameters of the haze particles. Polarization information such as shape model, scale distribution, etc. Comprehensive analysis of the light intensity information, polarization information and spectral information of the scattered light and the main beam can not only draw the light scattering law of the haze particles, but also reflect the physical characteristics of the haze particles, so as to better improve the optics. The accuracy of the system's inspection of haze particles, so the use of light beams to study the relevant parameters of haze particles is becoming more and more important. This article first analyzes the physical parameters of the haze particles, and elaborates on the scattering theory of the laser beam by the haze example. In the artificially simulated haze environment, by changing the haze concentration and measuring distance, the attenuation change of the light intensity is measured. According to the Mie scattering theoryi, the direct-view and non-direct-view single-scattering models of haze spherical particles analyze the corresponding parameter relationships.
