Abstract
A light-guide optical element (LOE) and methods of manufacture are disclosed. The LOE includes a transparent substrate having a first refractive index, the substrate having a pair of parallel external surfaces along a length thereof, and a plurality of mutually parallel at least partially reflective internal surfaces, the mutually parallel internal surfaces being angled obliquely relative to the pair of external surfaces; and a transparent polymer resin encapsulating at least a part of the substrate to form an encapsulated structure, the polymer resin having a second refractive index that is matched to the first refractive index; wherein the encapsulated structure comprises a pair of parallel external surfaces of optical quality formed from the resin.
