【摘要】 传统大气偏振建模方法回避了对散射过程的描述,偏振角的物理意义不明确。本文采用电矢分量法描述光波,利用洛伦茨-米散射理论的相关公式,分析自然光入射下的单次瑞利散射过程。利用散射光电矢量的大小计算偏振度,利用其方向定义偏振角。仿真结果表明,本文合理解释了偏振角的物理意义,且算法能够正确计算理想情况下大气偏振信息。更多还原

【Abstract】 In the traditional model of skylight polarization pattern under ideal atmospheric conditions,polarization angle has unclear physical significance for the lack of analysis of the scattering process.In this paper,electric field intensity vector is used to describe light waves,and some interrelated formulas in theory of Lorenz-Mie scattering are used to analyze the single Reyleigh scattering process on condition that the incidence light is natural light. Through the analysis,the electric field intesity vector of scattering light can be calculated.Therefor,polarization degree is calculated by the model of the vector,and polarization angle is defined by its direction.The results of simulation experiment show that polarization angle is defined reasonably and the arithmetic is well and effectively.更多还原
