We present a versatile, non-interferometric method for generating vector fields and vector beams which can produce all the states of polarization represented on a higher-order Poincaré sphere. The versatility and non-interferometric nature of this method is expected to enable exploration of various exotic properties of vector fields and vector beams. To illustrate this, we study the propagation properties of some vector fields and find that, in general, propagation alters both their intensity and polarization distribution, and more interestingly, converts some vector fields into vector beams. In the article, we also suggest a modified Jones vector formalism to represent vector fields and vector beams.
我们提出了一种通用的、非干涉式方法来生成矢量场和矢量光束，该方法可以产生高阶庞加莱球面上所表示的所有偏振态。预计这种方法的通用性和非干涉特性将有助于探索矢量场和矢量光束的各种奇异特性。为了说明这一点，我们研究了一些矢量场的传播特性，发现一般来说，传播会改变它们的强度和偏振分布，更有趣的是，会将一些矢量场转换为矢量光束。在本文中，我们还提出了一种改进的琼斯矢量形式来表示矢量场和矢量光束。
