APPARATUS FOR DIGITAL PROJECTION USING HOLOGRAPHIC TECHNIQUES
First Claim
1. An apparatus for generating and displaying a projected digital image, the apparatus comprising:
- an actuator;
a holographic encoded medium comprising a holographic pattern, the holographic encoded medium disposed in operable communication with the actuator;
a light source configured to produce a coherent light disposed in optical communication with the holographic encoded medium; and
a controller operable to control synchronization of the coherent light from the light source with a position of the holographic encoded medium as driven by the actuator to produce the projected digital image on a projection surface based on directing the coherent light to different portions of the holographic pattern at different times.

Abstract
An apparatus for generating and displaying a projected digital image includes an actuator, a holographic encoded medium with a holographic pattern, a light source, and a controller. The holographic encoded medium is disposed in operable communication with the actuator. The light source is configured to produce a coherent light disposed in optical communication with the holographic encoded medium. The controller is operable to control synchronization of the coherent light from the light source with a position of the holographic encoded medium as driven by the actuator to produce the projected digital image on a projection surface based on directing the coherent light to different portions of the holographic pattern at different times.

11. A method for generating and displaying a projected digital image from an apparatus, comprising:
-
enabling an actuator to move a holographic encoded medium comprising a holographic pattern, the holographic encoded medium disposed in operable communication with the actuator; directing a coherent light from a light source at a first time to synchronize with a first portion of the holographic encoded medium as driven by the actuator; directing the coherent light from the light source at a second time to synchronize with a second portion of the holographic encoded medium as driven by the actuator; and producing the projected digital image on a projection surface based on directing the coherent light to different portions of the holographic pattern at different times. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
