Uses of spatial light modulators for colour optical processing

摘要

In this work we review the use of spatial light modulators (SLMs) for optical processing applications involving colour management. We include pioneering results in collaboration with H. J. Caulfield, where colour information was introduced onto an optical correlator by means of gratings with different orientation, frequency and amplitude. Nowadays SLMs are used to manage colour in applications that include colour digital holography, multispectral and hyperspectral filtering, polarimetric sensing, or pulse shaping systems. Here we review techniques for the spectral characterization of liquid crystal SLMs and some of the advances in their use for some of the above-mentioned applications.
