Energy propagation and transverse anderson localization with two-dimensional, light field and holographic relays

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.
