Abstract

An ultra high-resolution volumetric three-dimensional (3D) display system comprises an image chamber, and an addressing system to direct a beam of electromagnetic energy at a first wavelength to slice through the image chamber. The beam of electromagnetic energy slices the image chamber along a first axis to provide an image slice. The addressing system comprises a line generator to shape the beam into a line extended along a second axis. An imaging system delivers the electromagnetic energy at a second wavelength to an area within the provided image slice. The line is moved along a third axis to form a three dimensional (3D) image.

Claims (52)

1. A three-dimensional (3D) display system, comprising:

an image chamber;

an addressing system to direct a beam of electromagnetic energy at a first wavelength to slice through the image chamber along a first axis, the beam having a cross-section in a first plane perpendicular to the first axis, wherein the addressing system comprises a line generator to shape the cross-section of the beam into a line extended along a second axis in the first plane to illuminate a second plane in the image chamber to provide an image slice; and

an imaging system delivering electromagnetic energy at a second wavelength to an area within the provided image slice, wherein the line is moved along a third axis to form a three dimensional (3D) image.

2. The 3D display system of claim 1 , wherein the line generator comprises

a collimating optics to collimate the beam;

a slicing optics to slice the collimated beam into a plurality of beamlets;

a rotating optics to rotate the beamlets to form the line;

a homogenization optics coupled to the rotating optics to homogenize the line; and

a focusing optics to control the line.

3. The 3D display system of claim 1 , wherein the line generator comprises

a collimating optics to form the beam;

a plurality of cylindrical lenses coupled to the collimating optics to convert the collimated beam into a line-shaped beam.

4. The 3D display system of claim 1 , wherein the beam is processed along the second axis independently from the first axis.

5. The 3D display system of claim 1 , wherein the width of the line controls the depth of each voxel in the display.

6. The 3D display system of claim 1 , wherein the addressing system comprises a polygon scanner that comprises one of a polygon shaped prism and a polygon shaped mirror to move the line along the third axis.

7. The 3D display system of claim 1 , further comprising a control system to synchronize the addressing system and the imaging system.

8. The 3D display system of claim 1 , wherein the image chamber comprises

two frequency two step upconversion nanoparticle material.

9. The 3D display system of claim 1 , wherein the image chamber comprises

two frequency two step upconversion microparticle material.

10. The 3D display system of claim 1 , wherein the image chamber comprises

two frequency two step upconversion bulk crystal.

11. The 3D display system of claim 1 , wherein the imaging system comprises

a digital micromirror device, a grating light valve, a liquid crystal display, or any combination thereof.

12. A method to produce a three-dimensional image, comprising:

directing a beam of electromagnetic energy at a first wavelength to slice through an image chamber along a first axis, wherein the beam has a cross-section in a first plane perpendicular to the first axis that is shaped into a line extended along a second axis in the first plane to illuminate a second plane in the image chamber to provide an image slice; and

delivering the electromagnetic energy at a second wavelength to an area within the provided image slice, wherein the line is moved along a third axis to form a three dimensional (3D) image.

13. The method of claim 12 , further comprising

collimating the beam;

slicing the collimated beam into a plurality of beamlets;

rotating the beamlets to form the line;

homogenizing the line; and

controlling the line.

14. The method of claim 12 , further comprising

collimating the beam; and

converting the collimated beam into a line-shaped beam.

15. The method of claim 12 , further comprising

processing the beam along the second axis independent from the first axis.

16. The method of claim 12 , wherein the width of the line controls the depth of each voxel in the display.

17. The method of claim 12 , further comprising

move the line along the third axis using a polygon scanner.

18. The method of claim 12 , further comprising

synchronizing the addressing system and the imaging system.

19. The method of claim 12 , wherein the image chamber comprises

two frequency two step upconversion nanoparticle material.

20. The method of claim 12 , wherein the image chamber comprises

two frequency two step upconversion microparticle material.

21. The method of claim 12 , wherein the image chamber comprises

two frequency two step upconversion bulk crystal.

22. The method of claim 12 , wherein the imaging system comprises

a digital micromirror device, a grating light valve, a liquid crystal display, or any combination thereof.
