Paper Abstract

The advantages of phase-encoded computer-generated-hologram (CGH) are high diffraction efficiency and the ability to reconstruct images on-axis. These advantages are very fundamental and important for many applications. The implementation of phase-encoded CGH by using electrical-addressable liquid crystal television (LCTV) with pure phase-modulation provides the ability for programmable optical interconnections, optical neural systems, optical switches etc. In this paper we adopt the iterative Fourier transform algorithm to design a pure phase CGH. We also report the modulation characteristics of LCTV and its application for displaying the phase-encoded CGH. Criterions for evaluating the quality of output images are proposed.
