Abstract

A method of printing a holographic 3D image is provided. The method includes forming sub-voxels on a hologram recording material, the sub-voxels including one or more colors.

First claim

What is claimed is:

1. A method of recording a holographic 3D image, the method comprising:
forming a first sub-voxel on a hologram recording material, wherein said forming of the first sub-voxel comprises
passing a first light through a spatial light modulator (SML); and
recording color data of the first light on the first sub-voxel of the hologram recording material;

moving the hologram recording material by a distance corresponding to a size of a sub-voxel;
forming a second sub-voxel on a hologram recording material, wherein said forming of the second sub-voxel comprises
passing a second light through the SML; and
recording color data of the second light on the second sub-voxel of the hologram recording material,

wherein each of the first and second sub-voxels consists of one or two colors.

2. The method of claim 1 , further comprising:
forming additional sub-voxels by iteratively repeating the forming and moving; and
forming a sub-voxel 2D array configuration comprising the first sub-voxel, the second sub-voxel, and the additional sub-voxels.

3. The method of claim 2 , wherein each of the first sub-voxel, the second sub-voxel, and the additional sub-voxels comprises pieces of color data that is different from a piece of color data of an adjacent sub-voxel in the 2D array configuration.

4. The method of claim 3 , wherein each of the first sub-voxel, and the second sub-voxel, and the additional sub-voxels comprises a different piece of location data.

5. The method of claim 2 , wherein, in the sub-voxel 2D array configuration, odd number rows of sub-voxels are shifted by a predetermined distance from even number rows of sub-voxels.

6. The method of claim 2 , wherein, in the sub-voxel 2D array configuration, odd number columns of sub-voxels are shifted by a predetermined distance from even number columns of sub-voxels.

7. The method of claim 1 , wherein the one or two colors are selected from a group consisting essentially of red, green, and blue.

8. A method of recording a holographic 3D image, the method comprising:
emitting a first light, a second light, and a third light from a first light source, a second light source, and a third light source, respectively;
splitting the first light into a first reference light and a first material light;
splitting the second light into a second reference light and a second material light;
splitting the third light into a third reference light and a third material light;
forming a first sub-voxel corresponding to the first material light and consisting of a first color on a hologram recording material;
moving the hologram recording material by a distance corresponding to a size of a sub-voxel;
forming a second sub-voxel corresponding to the second material light and consisting of a second color on the hologram recording material;
moving the hologram recording material by the distance corresponding to the size of the sub-voxel; and
forming a third sub-voxel corresponding to the third material light and consisting of a third color on the hologram recording material.

9. The method of claim 8 , wherein the forming of the first sub-voxel comprises emitting the first material light of the first color to a first location on the hologram recording material via a spatial light modulator (SLM) on which color data of the first color is displayed,
wherein the forming of the second sub-voxel comprises emitting the second material light of the second color to a second location on the hologram recording material via the SLM on which color data of the second color is displayed, and
wherein the forming of the third sub-voxel comprises emitting the third material light of the third color to a third location on the hologram recording material via the SLM on which color data of the third color is displayed.

10. The method of claim 9 , wherein the light of the first color is emitted by a first laser light source,
wherein the light of the second color is emitted by a second laser light source, and
wherein the light of the third color is emitted by a third laser light source.

11. The method of claim 8 , further comprising:
repeatedly and sequentially forming the first, second, and third sub-voxels to form a sub-voxel 2D array configuration.

12. The method of claim 11 , wherein the first, second, and third sub-voxels are adjacently arranged.

13. The method of claim 11 , wherein each of the first, second, and third sub-voxels comprises a different piece of location data.

14. The method of claim 11 , wherein, in the sub-voxel 2D array configuration, odd number rows of the first, second, and third sub-voxels are shifted by a predetermined distance from even number rows of the first, second, and third sub-voxels.

15. The method of claim 11 , wherein, in the sub-voxel 2D array configuration, odd number columns of the first, second, and third sub-voxels are shifted by a predetermined distance from even number columns of the first, second, and third sub-voxels.

16. The method of claim 8 , wherein the first, second, and third colors are red, green, and blue, respectively.

17. A method of printing a holographic 3D image, the method comprising:
forming a first sub-voxel comprising a first color and a second color on a hologram recording material;
moving the hologram recording material by a distance corresponding to a size of a sub-voxel;
forming a second sub-voxel comprising the second color and a third color on the hologram recording material;
moving the hologram recording material by the distance corresponding to the size of the sub-voxel; and
forming a third sub-voxel comprising the third color and the first color on the hologram recording material.

18. The method of claim 17 , wherein the forming of the first sub-voxel comprises recording color data regarding the first color and color data regarding the second color to a first location on the hologram recording material.

19. The method of claim 17 , wherein the forming of the second sub-voxel comprises recording color data regarding the second color and color data regarding the third color to a second location on the hologram recording material.

20. The method of claim 17 , wherein the forming of the third sub-voxel comprises recording color data regarding the third color and color data regarding the first color to a third location on the hologram recording material.

21. The method of claim 17 , further comprising:
repeatedly and sequentially forming the first, second, and third sub-voxels to form the sub-voxel 2D array configuration.

22. The method of claim 21 , wherein the first, second, and third sub-voxels are adjacently arranged.

23. The method of claim 21 , wherein each of the first, second, and third sub-voxels comprise a different piece of location data.

24. The method of claim 21 , wherein, in the sub-voxel 2D array configuration, odd number rows of the first, second, and third sub-voxels are shifted by a predetermined distance from even number rows of the first, second, and third sub-voxels.

25. The method of claim 21 , wherein, in the sub-voxel 2D array configuration, odd number columns of the first, second, and third sub-voxels are shifted by a predetermined distance from even number columns of the first, second, and third sub-voxels.

26. The method of claim 17 , wherein the first, second, and third colors comprise red, green, and blue, respectively.
