Abstract
Ternary phase and amplitude modulations that use a reflective mode, 45° twisted nematic liquid-crystal spatial-light modulator are demonstrated. This use offers a simple method for implementation of ternary phase–amplitude filters with high resolution, high optical efficiency, and fast response time.Keywords
