Abstract

This paper describes a holographic display using liquid crystal panels from which holographic images can be perceived with both eyes. In the display, the hologram plane is composed of two high-resolution liquid crystal panels each with a pixel pitch of 10 microns (both horizontally and vertically) and 3840 (horizontal) × 2048 (vertical) pixels. The horizontal viewing zone is doubled by applying the viewing-zone enlargement method, which uses higher-order diffraction beams, to the high-resolution liquid crystal panels. In addition, obstacles resulting from conjugate beams are eliminated using the modified single-sideband method. As a result, the viewing zone of the display is 6.5 cm, which is equivalent to the distance between pupils, at a viewing distance of 90 cm. Thus, moving three-dimensional holographic images free off conjugate beam obstacles could be perceived with both eyes.
