Abstract
A laser light show device and method produces a surface projected or suspended holographic image, and includes multiple image projectors. One image projector provides the object image information representing the primary subject. For surface projections, additional background image projectors provide background image information generated using a wobbler plate-reflected beam diffracted through a spherical lens, a beam unidimensionally diffracted through a rotating cylindrical amorphic dipolyhedral lens, and a beam diffracted through multiple diffraction gratings. A suspended holographic image is produced by parabolically focusing multiple images projected onto a spherical image screen.
Claims2
A method for generating holographic images, comprising the steps of:
- modulating a plurality of laser light beams with image information;
- projecting said modulated laser light beams substantially equiangularly about the equator of and onto a substantially spherical image reflector;
- reflecting images from said image reflector off of a first concave reflector having an apex disposed substantially opposite a first pole of said image reflector;
- and
- converging said image reflections at a point substantially opposite a second pole of said image reflector.
