Abstract

Aspects of the disclosure relate to methods, apparatus, and systems for oscillating transparent digital displays to generate a three-dimensional (3D) holographic image. A holographic imaging system includes a plurality of digital screens, wherein each screen of the plurality of digital screens is positioned parallel to an x-axis and a y-axis, and the screens are stacked along a z-axis perpendicular to the x-axis and the y-axis, a propulsion system configured to oscillate the plurality of digital screens along the z-axis, and a control system. The control system is configured to generate a digital image, display different slices of the digital image on the plurality of digital screens, and activate the propulsion system to oscillate the plurality of digital screens in synchronization with the display of the different slices on the screens to generate a three-dimensional (3D) image.

First claim

What is claimed is:

1. A holographic imaging system, the system comprising:
a plurality of transparent digital screens, wherein each screen of the plurality of transparent digital screens is positioned parallel to an x-axis and a y-axis, and the screens are stacked along a z-axis perpendicular to the x-axis and the y-axis;
a propulsion system configured to oscillate the plurality of transparent digital screens along the z-axis; and
a control system configured to:
generate a digital image,
instruct the plurality of transparent digital screens to display different image slices of the digital image,
send a signal to activate the propulsion system to oscillate the plurality of transparent digital screens in synchronization with the display of the different image slices on the plurality of transparent digital screens to generate a three-dimensional (3D) image, and
change at least one image slice displayed on at least one transparent digital screen of the plurality of transparent digital screens while the at least one transparent digital screen is oscillating.

2. The system of claim 1 , wherein the plurality of transparent digital screens are separated from each other by a fixed distance.

3. The system of claim 2 , wherein a maximum distance the plurality of transparent digital screens are oscillated is equal to the fixed distance.

4. The system of claim 1 , wherein:
a first set of digital screens of the plurality of transparent digital screens are separated from each other by a first distance; and
at least one other set of digital screens of the plurality of transparent digital screens are separated from each other by a second distance less than the first distance.

5. The system of claim 4 , wherein a maximum distance the plurality of transparent digital screens are oscillated is equal to the first distance.

6. The system of claim 1 , wherein the plurality of transparent digital screens comprises at least one of:
a liquid crystal display (LCD);
a light emitting diode (LED) display; or
an organic light emitting diode (OLED) display.

7. The system of claim 1 , wherein the plurality of transparent digital screens comprise:
flat digital screens; or
curved digital screens.

8. The system of claim 1 , further comprising:
a vacuum-sealed chamber configured to house the plurality of transparent digital screens and the propulsion system.

9. The system of claim 1 , wherein the propulsion system comprises:
at least one piston coupled to an outer edge of the plurality of transparent digital screens; and
a motor configured to actuate the at least one piston to oscillate the plurality of transparent digital screens along the z-axis based on the signal from the control system.

10. The system of claim 1 , wherein the propulsion system comprises:
an electromagnetic track in which the plurality of transparent digital screens are suspended by a magnetic field, wherein the control system is configured to vary a polarity of the magnetic field to oscillate the plurality of transparent digital screens along the z-axis.

11. A method for generating a holographic image, the method comprising:
generating a digital image via a control system;
instructing, via the control system, a plurality of transparent digital screens to display different image slices of the digital image, wherein each screen of the plurality of transparent digital screens is positioned parallel to an x-axis and a y-axis, and the plurality of transparent digital screens are stacked along a z-axis perpendicular to the x-axis and the y-axis;
activating, via the control system, a propulsion system to oscillate the plurality of transparent digital screens along the z-axis in synchronization with the display of the different image slices on the plurality of transparent digital screens to generate a three-dimensional (3D) image; and
changing, via the control system, at least one image slice displayed on at least one transparent digital screen of the plurality of transparent digital screens while the at least one transparent digital screen is oscillating.

12. The method of claim 11 , wherein the plurality of transparent digital screens are separated from each other by a fixed distance.

13. The method of claim 12 , wherein a maximum distance the plurality of transparent digital screens are oscillated is equal to the fixed distance.

14. The method of claim 11 , wherein:
a first set of digital screens of the plurality of transparent digital screens are separated from each other by a first distance; and
at least one other set of digital screens of the plurality of transparent digital screens are separated from each other by a second distance less than the first distance.

15. The method of claim 14 , wherein a maximum distance the plurality of transparent digital screens are oscillated is equal to the first distance.

16. The method of claim 11 , wherein the plurality of transparent digital screens comprises at least one of:
a liquid crystal display (LCD);
a light emitting diode (LED) display; or
an organic light emitting diode (OLED) display.

17. The method of claim 11 , wherein the plurality of transparent digital screens comprise:
flat digital screens; or
curved digital screens.

18. A control system for generating a holographic image, the control system comprising:
a memory; and
at least one processor coupled to the memory, wherein the at least one processor is configured to:
generate a digital image,
instruct a plurality of transparent digital screens to display different image slices of the digital image, wherein each screen of the plurality of transparent digital screens is positioned parallel to an x-axis and a y-axis, and the plurality of transparent digital screens are stacked along a z-axis perpendicular to the x-axis and the y-axis,
activate a propulsion system to oscillate the plurality of transparent digital screens along the z-axis in synchronization with the display of the different image slices on the plurality of transparent digital screens to generate a three-dimensional (3D) image, and
change at least one image slice displayed on at least one transparent digital screen of the plurality of transparent digital screens while the at least one transparent digital screen is oscillating.
