基于液晶的旋光效应，我们研制了一种结构紧凑、效率高的空变偏振控制光学器件。利用该装置，我们从线偏振光束产生了具有轴对称偏振的矢量光束。在本文中，我们描述的偏振分布和光束模式的测量特性在近场和远场区域，这些与理论预测进行比较。
Based on the optical rotatory effect of liquid crystal, we have fabricated a compact and efficient optical device for control of space-variant polarization. Using this device we generated vector beams that have axially-symmetric polarization from a linearly-polarized beam. In this paper, we describe the measured characteristics of polarization distributions and beam patterns in the near- and far-field regions, comparing these with theoretical predictions.
