Abstract

The present disclosure relates to systems and methods for translating optical beams.

First claim

What is claimed is:

1. A translational beam system comprising:
a belt disposed to be translated along at least one axis, wherein the belt comprises a plurality of lenses coupled thereto, wherein the belt comprises one or more apertures configured to allow a reference beam to pass therethrough; and
a spatial light modulator configured to cause an object beam to pass through one or more of the plurality of lenses as the belt is translated, wherein the one or more lenses cause the object beam to converge or diverge.

2. The system of claim 1 , wherein the plurality of lenses are arranged in a sequence based on at least the direction of translation of the belt.

3. The system of claim 1 , further comprising a plurality of rollers configure to cause the translation of the belt.

4. The system of claim 1 , wherein the translation of the belt is continuous.

5. The system of claim 1 , wherein the plurality of lenses comprise one or more holographic lenses.

6. The system of claim 1 , further comprising:
a holographic recording material, wherein the belt is spaced from the holographic recording material, wherein the plurality of lenses comprise one or more holographic lenses, wherein the spatial light modulator is configured to cause the object beam to pass through the one or more holographic lenses such that the one or more holographic lenses focus the object beam onto the holographic recording material; and
a light source configured to cause the reference beam to be incident on the holographic recording material such that the holographic recording material stores information based on interference between the reference beam and the object beam.

7. The system of claim 6 , wherein the holographic recording material comprises a photorefractive screen.

8. The system of claim 6 , wherein the one or more apertures include one or more slit apertures.

9. The system of claim 6 , wherein the translation of the belt is continuous and the storage of information on the holographic recording material is continuous.

10. A system for processing holographic stereograms, the system comprising:
a holographic recording material;
a belt spaced from the holographic recording material and disposed to be translated in a continuous circuit, wherein the belt comprises a plurality of holographic lenses coupled thereto and arranged in a prescribed pattern;
a spatial light modulator configured to cause an object beam to pass through the holographic lenses such that the holographic lenses focus the object beam onto the holographic recording material;
and a light source configured to cause a reference beam to be incident on the holographic recording material such that the holographic recording material stores information based on interference between the reference beam and the object beam, wherein the belt comprises one or more apertures configured to allow the reference beam to pass therethrough.

11. The system of claim 10 , wherein the holographic recording material comprises a photorefractive screen.

12. The system of claim 10 , wherein the plurality of holographic lenses comprises a spherical lens or a cylindrical lens, or both.

13. The system of claim 10 , wherein the one or more apertures include one or more slit apertures.

14. The system of claim 10 , further comprising a plurality of rollers configure to cause the translation of the belt.

15. The system of claim 10 , wherein the translation of the belt is continuous and the storage of information on the holographic recording material is continuous.
