Abstract

On the basis of polarized detection mechanism,the relationship between the polarization degree and the refractive index is established,and the change regulation on different refractive indexes combination is discussed.The results show that when the solar incident angle at the left of the intersection angle,the polarization degree is inversely proportional to the refractive index,and when the solar incident angle at the right of the intersection angle,the polarization degree is proportional to the refractive index.The D-values of polarization degree reaches the maximum at the solar incident angle 40°or 70°.To obtain polarization information in the suitable angle,the accuracy of the water remote sensing can be improved.

水体偏振遥感太阳入射角研究

在极化检测机理的基础上，建立了偏振度与折射率的关系，讨论了不同折射率组合的变化规律。结果表明，当太阳入射角位于相交角的左侧时，偏振度与折射率成反比，当太阳入射角位于相交角的右侧时，偏振度与折射率成反比。偏振度的d值在太阳入射角为40°或70°时达到最大值。在合适的角度获取偏振信息，可以提高水体遥感的精度。

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
