Abstract:
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.
