Abstract

The performance of optical readout of Digital Volume Reflection Holograms (DVRHs) introduced into a Spatial Light Modulator (SLM) is investigated. Liquid crystal SLMs have been used to control a two-dimensional light beam to achieve beam deflection, beam shaping, and holographic imaging. We use the spatial light modulator as a holographic element for DVRH. This is achieved by computing the DVRH numerically from multiple digital transmission holograms recorded at different wavelengths, and optically reading out the information from the DVRH that is introduced into the SLM. The effectiveness of the SLM to read out information from the DVRH with high wavelength selectivity is investigated.
