Abstract

Disclosed are image relay elements exhibiting transverse Anderson localization for light field and holographic energy sources. The relay elements may include a relay element body having one or more structures, where the structures can be coupled in series, in parallel and/or in stacked configurations. The structures may have multiple surfaces such that energy waves propagating therethrough the relay elements may experience spatial magnification or de-magnification.

Claims (19)

1. A device comprising:

a relay element formed of one or more structures, the relay element having a first surface, a second surface, a transverse orientation and a longitudinal orientation;

wherein the first surface has a surface area different than the second surface;

wherein the relay element comprises a sloped profile portion between the first surface and the second surface;

wherein energy waves propagating between the first surface and the second surface travel substantially parallel to the longitudinal orientation due to a substantially higher transport efficiency in the longitudinal orientation than in the transverse orientation;

wherein the energy waves passing therethrough the relay element result in spatial magnification or spatial de-magnification; and

whereby energy with a uniform profile presented to the first surface passes through the second surface to substantially fill a cone with an opening angle of +/−10 degrees relative to the normal to the second surface, irrespective of location on the second surface.

2. The device of claim 1 , wherein the energy waves passing through the first surface has a first resolution, wherein the energy waves passing through the second surface has a second resolution, and wherein the second resolution is no less than about 50% of the first resolution.

3. The device of claim 1 , wherein the relay element includes a plurality of elements in a stacked configuration in the longitudinal orientation, wherein a first element of the plurality of elements includes the first surface and wherein a second element of the plurality of elements includes the second surface.

4. The device of claim 3 , wherein the first element causes either spatial magnification or spatial de-magnification of the energy waves, and the second element causes either spatial magnification or spatial de-magnification of the energy waves.

5. The device of claim 3 , wherein the plurality of elements in the stacked configuration includes a plurality of faceplates.

6. The device of claim 5 , wherein the plurality of faceplates are loose coherent optical relays.

7. The device of claim 1 , wherein the relay element includes randomized refractive index variability such that the energy waves are localized in the transverse orientation.

8. The device of claim 1 , wherein the first surface is configured to receive the energy waves from an energy source unit, the energy source unit comprising a mechanical envelope having a width different than the width of at least one of the first surface and the second surface.

9. The device of claim 8 , wherein the mechanical envelope includes a projection system having a lens, and a plurality of energy source panels disposed adjacent to the lens, the plurality of energy source panels being planar, non-planar or combinations thereof.

10. The device of claim 9 , wherein the plurality of energy source panels are arranged in various configurations including at least one of tilted, aligned at an angle, staggered, on-axis, off-axis, rotated, parallel, perpendicular, or any combinations thereof.

11. The device of claim 9 , wherein the plurality of energy source panels are arranged in a radially-symmetrical configuration.

12. The device of claim 9 , wherein the projection system includes focused energy transmission through a waveguide, and further comprises a telecentric lens relay element at an off-aligned angle.

13. The device of claim 1 , wherein the first surface is either planar or non-planar, and the second surface is either planar or non-planar.
