Two-pixel computer-generated hologram with a zero-twist nematic liquid-crystal spatial light modulator

Not Accessible

Your library or personal account may give you access

Abstract

We present a method of producing a computer-generated hologram by use of a zero-twist linear nematic liquid-crystal spatial light modulator. A 2×1 macro pixel method is used; one pixel represents the real data, and one, the imaginary. A method is shown that produces both positive and negative analog amplitude modulation.
