偏振光在气溶胶中的传输特性研究
|
摘要
为了研究气溶胶介质多次散射效应对区域内偏振光传输特性的影响,通过CE318太阳分光计实测数据反演得到了区域内气溶胶微物理光学特性参数(光学厚度、粒子复折射率、粒子谱分布)。利用蒙特卡罗矢量辐射传输模型系统分析了粒子复折射率、粒子群有效半径、入射光偏振状态对传输特性的影响。研究结果表明:较小复折射率实部粒子的传输特性对复折射率实部变化敏感性较强;复折射率虚部是影响辐射传输特性的一个重要因素,虚部越大,吸收性越强,传输特性越差;粒子群有效半径越大,光波透射率就越低,反射率则越高;入射光偏振状态对传输特性的影响较小,相比其他类型的偏振光,水平偏振光的反射率和透射率受入射角的影响较大。
In order to study the aerosol multiple scattering effect on the transmission characteristics of polarized light in the region,we retrieve the microphysical optical parameters of the aerosol,including optical thickness,complex refractive index,particle spectrum distribution,through the inversion of the measured data from the CE318 solar spectrometer.The influence of the complex refractive index of particles,the effective radius of particle swarm and the polarization state of incident light on the transmission characteristics is analyzed through the Monte Carlo vector radiative transfer model.The results show that the transmission characteristics of the smaller particles are more sensitive to the real part change of the complex refractive index.In addition,with the increase of the imaginary part of the complex refractive index,as an important factor affecting the characteristics of radiation transmission,the absorption is stronger and the transmission characteristics is worse.If the effective radius of the particle group is larger,the transmittance of the light wave will be lower and the reflection rate will be higher.The polarization state of the incident light has little influence on the transmission characteristics.Compare to the other types of polarized light,the transmission and reflection rate of horizontally polarized light are greatly affected by the incident angle.
