Curved lightguide preserving incident ray angles and increasing eyebox/field of view

Background Lightguide technologies are widely used in augmented and virtual reality systems to improve compactness. Planar lightguide geometries are currently most common, but when expanding to a large field of view, planar lightguides become very wide and require a large range of light emission angles. Furthermore, since the eye rolls on a spherical...
