Abstract

Switchable, continuous, complex-amplitude modulation is demonstrated with two cascaded, twisted nematic liquid-crystal televisions (LCTV’s), both operating in phase- and amplitude-coupled modulation modes. The condition for full-range complex modulation is that one of the LCTV’s must provide a 2π-range phase modulation. A look-up table encoding method is proposed that permits the compensation of phase–amplitude coupling and nonlinearity in the two individual LCTV modulations. Experimental techniques for determining the LCTV-device parameters, for maximizing the phase-mostly modulation range and the amplitude-mostly modulation contrast, and for testing the complex-amplitude modulation are developed. Optical complex-amplitude Fresnel holograms are shown.
