Device with array of spinning microlenses to display three-dimensional images
First Claim
1. A device for displaying three-dimensional images comprising:
- an image display surface, wherein this image display surface emits or reflects light to display an image comprised of multiple small image elements, andan array of spinning microlenses, wherein each spinning microlens redirects light rays from one or more small image elements, wherein light rays exiting a spinning microlens define a conic or conic-section space over time, and wherein the image contents displayed by small image elements are coordinated with the movement of the spinning microlenses, through which those image contents are directed, to form a pattern of light rays with the proper content and directionality so as to create perception of three-dimensional images.

Abstract
This invention is a device for displaying three-dimensional images using an array of spinning microlenses. It can create high-resolution, large-scale, moving, three-dimensional images that can be viewed by people in different locations, with full parallax, without special eyewear. Unlike currently available methods, this invention: does not require special eyewear, works for multiple viewers, provides parallax in all directions, does not have a very restrictive viewing zone, does not produce only transparent images, does not require coherent light, is scalable to large displays, does not require liquid movement to adjust lens shape, and does not require complex systems to individually control large numbers of lenses.

14. A method for displaying three-dimensional images comprising:
-
emitting light from, or projecting light onto, a display surface so as to create an image, and redirecting light from points on this surface using an array of spinning microlenses, wherein the angular directions of the light rays exiting these microlenses form a light pattern that creates perception of three-dimensional images.
