We introduce an effective optical system to produce optical beams with arbitrary, inhomogeneous polarization states. Using our system, we are capable of generating vector beams with discretionarily chosen transverse complex fields in a straightforward way. We generate several different instances of well-known vector beams and the less common spirally polarized vector beams, as well as a full Poincaré beam. We visually show the continual transition between azimuthally and radially polarized beams via a collection of spirally polarized beams. We experimentally determine the polarization states of the generated beams and quantitatively assess the performance of our system. We find that the measured polarization distributions accurately coincide with the intended input polarization distributions.
我们介绍了一种有效的光学系统，用于产生具有任意非均匀偏振态的光束。使用我们的系统，我们能够以直接的方式生成具有任意选择的横向复场的矢量光束。我们生成了几种不同实例的著名矢量光束和不太常见的螺旋偏振矢量光束，以及一个完整的庞加莱光束。我们通过一系列螺旋偏振光束直观地展示了方位角偏振光束和径向偏振光束之间的连续过渡。我们通过实验确定了所产生光束的偏振态，并定量评估了我们系统的性能。我们发现测量得到的偏振分布与预期的输入偏振分布精确吻合。
