Abstract

Disclosed are systems and methods for manufacturing energy relays for energy directing systems. Methods and devices are disclosed for forming random and non-random patterns of energy relay materials with energy localization properties. Methods and devices are disclosed for forming energy relays of different shapes.

Claims (17)

1. A fixture for defining a constrained space configured to accommodate one or more energy relay materials therein, the fixture comprising:

a plurality of abutting adjustable walls extending along a longitudinal direction and defining a constrained space therebetween, each wall comprising an end portion and a side portion, and

wherein the adjustable walls are operable to vary a transverse dimension of at least a portion of the constrained space along the longitudinal direction by an adjustment to positions of the adjustable walls relative to one another in a transverse direction, perpendicular to the longitudinal direction; and

wherein the adjustment comprises abutting and sliding the end portion of a first wall against the side portion of a second wall in a first direction, and abutting and sliding the side portion of the first wall against the end portion of a third wall in a second direction; and

wherein each of the adjustable walls is configured to slide in synchrony with other adjustable walls to maintain a closed perimeter of the constrained space while defining the transverse dimension thereof.

2. The fixture of claim 1 , wherein the adjustable walls are configured to move relative to one another without creating any gaps in the walls of the constrained space.

3. The fixture of claim 1 , wherein the constrained space is defined by four walls.

4. The fixture of claim 3 , wherein a first and a second wall of the four walls are opposing one another.

5. The fixture of claim 4 , wherein a third and fourth wall of the four walls are opposing one another, and perpendicular to the first and second walls.

6. The fixture of claim 1 , wherein at least one adjustable wall comprises a guide along which an abutting wall position is adjustable.

7. The fixture of claim 1 , wherein at least one adjustable wall is operable to slide along a guide of an adjacent wall while oriented perpendicularly to the adjacent wall.

8. The fixture of claim 1 , wherein each wall of the plurality of walls comprises an end portion and a side portion, the end portion of a first wall configured to abut and slide against the side portion of a second wall in a first direction, and the side portion of the first wall configured to abut and slide against the end portion of a third wall in a second direction.

9. The fixture of claim 8 , wherein each side portion comprises a protrusion for defining a portion of the constrained space, and each end portion comprises a cutout configured to accommodate the protrusion of an abutting side portion such that there are no gaps between abutting side and end portions.

10. The fixture of claim 8 , wherein the first and second directions are perpendicular.

11. The fixture of claim 1 , wherein each of the plurality of walls comprises a portion of an inverse energy relay element shape.

12. The fixture of claim 1 , wherein a configuration of the plurality of adjustable walls defines an inverse shape of a tapered energy relay.

13. The fixture of claim 1 , wherein each of the adjustable walls is configured to slide in synchrony with other adjustable walls to apply equal force along the transverse direction to at least a portion of the one or more energy relay materials in the constrained space.
