Abstract
The present disclosure relates to systems and methods for translating optical beams.
Claims20
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;
- 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 that the one or more lenses cause the object beam to converge or diverge.
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.
1 more element
The system of aspect 11, wherein the holographic recording material comprises a photorefractive screen.
A system comprising:
- a first spatial light modulator for displaying one or more diffraction lenses;
- and
- a second spatial light modulator configured to cause an object beam to pass through the one or more diffraction lenses such that the one or more diffraction lenses cause the object beam to diffract, wherein a focal location of the diffracted object beam is shifted based at least on a configuration of the one or more diffraction lenses.
