在单个数字全息图上复用200种模式

Multiplexing 200 modes on a single digital hologram

Carmelo Rosales-Guzmán, Nkosiphile Bhebhe, Nyiku Mahonisi, Andrew Forbes

摘要:

光的空间形状的按需剪裁在各种各样的研究领域中具有很大的相关性。计算机控制的设备,如空间光调制器(SLM)或数字微镜设备(DMD),为此提供了非常准确,灵活和快速的全息手段。值得注意的是,数字全息术提供了同时产生多个光束(复用),这是一种在许多领域具有众多应用的工具。在这里,我们提供了一个关于光束复用的独立教程。通过几个实例,逐步引导读者了解光束整形和复用的过程。此外,对SLM的复用能力进行了定量分析,对单个SLM上可以复用的最大光束数进行了分析,在单个全息图上显示了大约200种模式。

英文摘要:

The on-demand tailoring of light's spatial shape is of great relevance in a wide variety of research areas. Computer-controlled devices, such as Spatial Light Modulators (SLMs) or Digital Micromirror Devices (DMDs), offer a very accurate, flexible and fast holographic means to this end. Remarkably, digital holography affords the simultaneous generation of multiple beams (multiplexing), a tool with numerous applications in many fields. Here, we provide a self-contained tutorial on light beam multiplexing. Through the use of several examples, the readers will be guided step by step in the process of light beam shaping and multiplexing. Additionally, on the multiplexing capabilities of SLMs to provide a quantitative analysis on the maximum number of beams that can be multiplexed on a single SLM, showing approximately 200 modes on a single hologram.
