Abstract

Spatial Light Modulators (SLMs) have advanced the fields of complex and structured light. These Liquid-Crystal-on-Silicon (LCoS) based devices allow for the dynamic modulation of both the amplitude and phase of light. This tutorial-type talk will provide an overview of the working principle of Spatial Light Modulators (SLMs). We will first look at the mechanism as to how these devices operate, followed by how to setup your own SLM, as well as the motivation to calibrate these devices. We will look at how digital holograms can be generated, as well as some common problems that the user might encounter. Finally, we will discuss some applications which make use of SLMs.
