Methods for improvement of spatial light modulator image rendering
Résumé
Image rendering of spatial light modulators (SLMs) is often degraded by various effects. Some efficient methods to get around nonuniformity, nonlinearity, and remanence and improve image rendering are presented. Optical laboratory results are presented for an analog ferroelectric liquid-crystal SLM using a high-speed camera. Focus is made on a preprocessing compensation method, using a spatialdependant correction table. A high-speed "on-the-fly" implementation is also suggested.
