摘要
矢量光束独特的空间偏振结构使之应用于空间偏振编码成为可能。提出了一种用一阶矢量光束的偏振分布进行极角空间编码的方法。通过矢量光束生成、光束偏振分布再调制实现了空间编码光束的生成,并采用斯托克斯参数法对空间编码光束进行检测。实验结果证实了一阶矢量光束应用于极角空间偏振编码的可行性,为基于空间偏振编码的激光驾束制导提供了新方法。
The unique spatial polarization structure of vector beam make it potential application to spatial polarization encoding.A method is presented to encoding the polar angle by the polarization structure of first order vector beam.Spatial polarization encoding beams are obtained by generation of first order vector beam and re-modulation of the polarization distribution of first order vector beam.Spatial polarization decoding is accomplished by measuring the Stokes parameters.The experimental results confirm that the method feasibility,which provides a new method of spatial coding for the laser beam riding guidance
