Abstract

Spatial light modulators (SLMs) are versatile devices used for optical studies. These instruments have a wide area of application in photonics. Additionally, SLMs have potential utility in different applications, such as biomedical applications, laser based surgery for precise cutting and as optical tweezers to separate cells in a petri container. However, the high cost of SLM devices prevents their widespread use in many areas, including industrial areas and scientific research laboratories. This paper demonstrates how to design a digital light processor (DLP) based low-cost SLM and describes how to obtain structured electromagnetic waves with the designed SLM. Therefore, this research was undertaken to design and produce a low-cost SLM device for optical applications. For this purpose, two prerequisites had to be fulfilled, the first was to use suitable components of a projection device with DLP-based digital micro-mirror device (DMD), and the second was to eliminate unnecessary SLM components from the system. Finally, holographic images reflected on the SLM screen were created by using Mathematica software program to change the amplitude and phase of the electromagnetic waves in order to obtain the structured electromagnetic waves.

利用数字光处理器的空间光调制器设计和结构电磁波的产生

空间光调制器(slm)是一种用于光学研究的多功能器件。这些仪器在光子学中有着广泛的应用领域。此外，slm在不同的应用中具有潜在的实用性，例如生物医学应用，用于精确切割的激光手术以及用作分离培养皿容器中的细胞的光学镊子。然而，SLM器件的高成本阻碍了其在许多领域的广泛应用，包括工业领域和科研实验室。本文介绍了如何设计一种基于数字光处理器(DLP)的低成本SLM，并描述了如何利用所设计的SLM获得结构化电磁波。因此，本研究旨在设计和生产一种用于光学应用的低成本SLM器件。为此，必须满足两个先决条件，第一是使用基于dlp的数字微镜装置(DMD)的投影装置的合适组件，第二是从系统中消除不必要的SLM组件。最后，利用Mathematica软件程序改变电磁波的振幅和相位，生成反射在SLM屏幕上的全息图像，从而得到结构化电磁波。
