Abstract

A cost-effective and reliable liquid crystal spatial light modulator (SLM) system is developed for light modulation and holographic recording of variable data in photopolymer material. It is made by reverse engineering a mobile phone with a liquid crystal display (LCD) of resolution 84×48 pixels. The SLM is based on a detached LCD panel with drivers, a personal computer system, an interface to provide data, and the software for uploading data. The SLM works well in the transmissive mode, and the transmitted laser beam is modulated according to the electronic data input to the panel from a personal computer. The SLM is implemented with good transmission efficiency and image contrast for holographic data recording and related experiments, and is observed as a very cost-effective option for light modulation.
