Complex modulation with a twisted-nematic liquid-crystal spatial light modulator: double-pixel approach.

I modify the double-phase holographic code to implement complex modulation with a transmission twisted-nematic liquid-crystal display. This device is employed in the mostly phase configuration, for which the phase modulation is coupled with a nonconstant amplitude modulation. The modified double-phase code implements arbitrary complex modulation employing the constrained complex modulation of the display.

Double-phase holograms implemented with phase-only spatial light modulators: performance evaluation and improvement.

We propose modified hologram cells (or macropixels) for the computer-generated double-phase holograms (DPHs), based on pixelated phase-only spatial light modulators (SLMs). Such modified DPHs exhibit a substantially improved signal-to-noise ratio, in comparison with the conventional ones. The modified macropixels are formed by arrays of either 1 x 2 or 2 x 2 SLM pixels.
