Interactive holographic display device
First Claim
1. A display apparatus configured to produce an interactive three-dimensional holographic image, comprising:
- one or more coherent light sources configured to produce one or more beams, based on obtained image data of an object to display;
a plurality of sub-deflection modulators each configured to deflect a beam of the one or more beams a deflection distance from a center of a micro lens, wherein the beam continues in a direction after deflection that is approximately parallel to an initial direction of the beam prior to deflection;
a lens assembly comprising a plurality of micro lenses having the micro lens configured to direct the one or more beams to form a holographic image of the object using a deflection angle, wherein the deflection distance controls where the lens assembly directs the one or more beams;
one or more optical sensors configured to obtain information regarding whether an interactive object interrupts the one or more beams; and
a processor configured to determine a location of the interactive object with respect to the holographic image, based on the obtained information from the one or more optical sensors.

Abstract
A display apparatus configured to produce an interactive three-dimensional holographic image is disclosed. The display apparatus can include one or more coherent light sources configured to produce one or more beams, based on obtained image data of an object to display, and a lens assembly configured to direct the one or more beams to form a holographic image of the object. The lens assembly can include a collimating lens and a lens capable of beam steering one or more beams, including a micro-lens assembly with at least one micro-lens configured to generate a plurality of beams associated with a plurality of desired viewing angles. One or more optical sensors can be configured to obtain information regarding whether an interactive device interrupts the one or more beams, and a processor unit can determine a location of the interactive device with respect to the holographic image.
