Abstract

A holographic display device for displaying a 3-dimensional image has a cylindrical casing and a horizontally-placed concave or convex paraboloidal hologram in order to project an upright orthoscopic image having both horizontal and vertical parallaxes, and having a wide field of view. The hologram may be illuminated by a point source of coherent light, preferably a high-efficiency semiconductor laser diode, securely attached at the bottom of the cylindrical casing below the hologram. The hologram and the beam expander lens to illuminate the hologram may be removed, and the mirror to change the direction of the coherent light may be vibrated so that the coherent light projects dynamic line figures on a ceiling above the holographic display device. This invention relates to holographic display devices for displaying a 3-dimensional image, and the principal use of the invention is for optical decoration.
