Abstract
A holographic projection system is disclosed for cost-effectively generating “real image” holographic images. In at least one embodiment, the system provides an at least one primary image source configured for projecting a primary image via an at least one light ray. A computing device is in communication with the at least one primary image source and configured for providing the primary image to be subsequently projected by the at least one primary image source. A curved reflector is positioned and configured for receiving and reflecting the at least one light ray toward a focal point of the reflector, the at least one reflected light ray converging at an image point so as to create a hologram of the projected primary image at the image point, with said hologram being viewable by an at least one observer.
Claims20
A holographic projection system comprising:
- a reflector having a curved shape, the reflector positioned and configured for receiving and reflecting an at least one light ray toward a focal point of the reflector, the reflector constructed out of a transparent or semi-transparent material;
- an at least one primary image source configured for projecting at least a portion of an at least one primary image via an at least one light ray toward a reflection location on the reflector;
- and
- a computing device in communication with the at least one primary image source and configured for providing the at least one primary image to be subsequently projected by the at least one primary image source;
- whereby, the at least one light ray projected by the at least one primary image source is reflected by the reflector toward the focal point thereof, the at least one reflected light ray converging at an image point positioned a distance in front of the reflector, between an at least one observer and the reflection location of the at least one reflected light ray, and at a height that is between an upper edge of the reflector and an opposing lower edge of the reflector, so as to create a hologram of each of the projected at least one primary image at the image point.

A holographic projection system comprising:
- a reflector having a curved shape, the reflector positioned and configured for receiving and reflecting an at least one light ray toward a focal point of the reflector, the reflector constructed out of a transparent or semi-transparent material and having one of a spherical, semi-spherical, cylindrical or conical shape;
- a plurality of primary image sources each configured for projecting an at least one primary image, independent of the other primary image sources, via an at least one light ray toward a unique reflection location on the reflector as compared to the other primary image sources;
- and
- a computing device in communication with the primary image sources and configured for providing the at least one primary image to be subsequently projected by the primary image sources;
- whereby, the at least one light ray projected by each of the primary image sources is reflected by the reflector toward the focal point thereof, the at least one reflected light ray converging at an image point positioned a distance in front of the reflector, between an at least one observer and the reflection location of the corresponding reflected light ray, and at a height that is between an upper edge of the reflector and an opposing lower edge of the reflector, so as to create a hologram of each of the projected at least one primary image at the image point, each hologram being viewable by the at least one observer within a corresponding viewing angle based on the reflection location of the corresponding reflected light ray.

A holographic projection system comprising:
- a curved reflector having one of a spherical, semi-spherical, cylindrical or conical shape, the reflector positioned and configured for receiving and reflecting an at least one light ray toward a focal point of the reflector;
- a plurality of primary image sources radially arranged about a circumference of the reflector and configured for cooperating to project an at least one primary image as a three-dimensional hologram that is viewable from about the entire circumference of the reflector;
- the at least one primary image being radially divided into a quantity of primary image slices equal to the quantity of primary image sources;
- each of the primary image sources configured for projecting one of the primary image slices via an at least one light ray toward a unique reflection location as compared to the other primary image sources, such that adjacent ones of the primary image sources project corresponding adjacent ones of the primary image slices;
- and
- a computing device in communication with the primary image sources and configured for providing the primary image slices to be subsequently projected by the primary image sources;
- whereby, the at least one light ray projected by each of the primary image sources is reflected by the reflector toward the focal point thereof, the at least one reflected light ray converging at an image point positioned a distance in front of the reflector, between an at least one observer and the reflection location of the corresponding reflected light ray, so as to create a three-dimensional hologram of the projected at least one primary image at the image point, the hologram of each primary image slice being viewable by the at least one observer within a corresponding viewing angle based on the reflection location of the corresponding reflected light ray.
