Design and compiling of laser propagation simulation software in atmospheric environment

As development of laser technology, the study of the characteristic of laser atmospheric propagation is always hot spot in laser domain. Using theoretical models of laser atmospheric propagation, a simulation system is researched by implementing a scientific method of software development. This simulation system can simulate the radiate property of laser propagation in atmosphere and the course of laser propagation. This theoretical model of atmospheric propagation is based on Lambert-Beer law, combined with other classic theoretical model such as Rayleigh scattering and Mie scattering. Multiple scattering theory models are used when simulating the laser propagation in smoke or fog. In calculation, the atmosphere environment is divided into layer. An appropriate model is selected for calculation in each layer in order to enhance the stimulation precision. The figure of light spot is drawn along transmission space.
