Abstract
Described are various embodiments of space-compressing methods, materials, devices, and systems, and imaging or optical devices and systems using same. In one embodiment, an optical system comprises an optical convergence element having a defined optical path convergence distance and disposed so to produce converging optical rays along an optical convergence path to converge at said distance; an optical space-compression medium disposed along the optical convergence path to intersect the converging optical rays to compress a resulting optical convergence distance by imparting an inward transverse translation of the converging optical rays while substantially maintaining respective incident convergence angles upon output.
