摘　　要：介绍了在激光偏振成像研究中,激光在大气传输中的散射光偏振特性的基本表示方法,根据Rayleigh散射和Mie散射理论,通过传输Mueller矩阵求解,分别对大气分子散射和气溶胶散射的单次偏振特性建立理论模型,并通过数值计算模拟的方法研究大气分子和气溶胶对自然光、水平线偏振光和45°线偏振光的偏振特性影响,最后介绍了用矢量传输方程来解决大气散射光多次散射偏振问题.The basic method of describing the polarization characteristics of atmospheric scattering light is discussed. According to the Rayleigh and Mie scattering theories, transfer Mueller matrix is given to respectively establish the models for the single polarization characteristic of atmosphere molecule and aerosol scattering lights. Meanwhile, through simulating the values calculation, the polarization characteristics of nature light, horizontal linear polarization light and 45°linear polarization light are studied, which are influenced by the atmosphere molecule and aerosol. Lastly, a method of vector transfer equation is given to deal with the polarization problems when the atmospheric scattering light scatters more times.
