Abstract

An investigation is made of means to the standardization of methods for parameter characterization in the cases of spatial light modulators of optically addressed, electrically addressed, amplitude-modulating, and phase-modulating types, with a view to recommendations for future practice. The speed, resolution, and visibility parameters are noted to compare well irrespective of modulator type; phase and amplitude modulating devices cannot be directly compared, however, due to the fundamentally different ways that parameters are measured for each. To be meaningful, the MTF for an optically-addressed device must be accompanied by speed and illumination data. Lifetimes should be specified for all devices.
