We discuss a class of synthetic phase holograms (SPHs) applied to the generation of vector fields. Each SPH encodes the transverse components of the vector field, modulated by different linear phase carriers. Such components, which are spatially separated by the carriers, are modulated by appropriate orthogonal polarizations. A final stage that makes the components collinear allows the generation of the vector field. We assess the efficiency and accuracy of the different SPHs, in the task of generating vector fields. The proposal is illustrated by the implementation of vector Bessel beams, which are experimentally generated in a setup based on a phase spatial light modulator.

使用合成相位全息图生成矢量光束

我们讨论了一类应用于矢量场生成的合成相位全息图 (SPH)。每个 SPH 编码矢量场的横向分量，由不同的线性相位载波调制。这些在空间上被载波分隔的分量通过适当的正交极化进行调制。使组件共线的最后阶段允许生成矢量场。我们在生成矢量场的任务中评估了不同 SPH 的效率和准确性。该提议通过矢量贝塞尔光束的实现来说明，这些光束是在基于相位空间光调制器的设置中通过实验生成的。
