论文摘要
复杂的矢量模式由于其引人入胜的特性及其在各种各样的研究领域中发现的许多应用而成为了近来的话题。即使可以通过多种方式生成此类模式,数字全息图作为最灵活和多才多艺的方式之一。沿着这条线,由于其较高的刷新率,数字微旋转设备(DMDS)在最近的时间内越来越受欢迎,这允许以KHz速率生成矢量模式。但是,大多数技术都受到可以生成的矢量模式的多样性的限制,或者是通过切换的速度的。在这里,我们提出了一种基于随机编码概念的技术,该技术允许以DMD的刷新速率限制在速度下生成任意向量光束。我们的技术将在研究领域(例如光学通信,激光材料处理和光学操纵等)中具有很大的意义。
Complex vector modes have become topical of late due to their fascinating properties and the many applications they have found across a broad variety of research fields. Even though such modes can be generated in a wide variety of ways, digital holography stands out as one of the most flexible and versatile. Along this line, Digital Micromirror Devices (DMDs) have gain popularity in recent time due to their high refresh rates, which allows the generation of vector modes at kHz rates. Nonetheless, most techniques are limited either by the diversity of vector modes that can be generated or by the speed at which they can be switched. Here we propose a technique based on the concept of random encoding, which allows the generation of arbitrary vector beams at speeds limited only by the refresh rate of the DMD. Our technique will be of great relevance in research fields such as optical communications, laser material processing and optical manipulation, amongst others.
