Title:
仮想現実および拡張現実ニアアイディスプレイ用の自由形状ナノ構造面
Document Type and Number:
Japanese Patent JP6892827
Kind Code:
B2
Abstract:
A near eye display includes at least one of a combiner, a secondary mirror, and a waveguide having a freeform nanostructured surface. The freeform nanostructured surface encompasses a freeform surface, a nanostructured surface or a combination of both the freeform surface and the nanostructured surface. The freeform nanostructured surface can be incorporated into a combiner or a secondary mirror in the near eye display in a compact folded geometry, wherein an anamorphic or freeform optic can be optically intermediate an image source and the freeform nanostructured surface. The nanostructured surface can include a meta-grating operable across the visible spectrum. The meta-grating includes meta-atoms configured to provide a given efficiency at the desired wavelengths in reflection.
