Embodiment Construction

[0028] The present disclosure relates to HMDs with thin holographic component (THC) based volumetric (thick) SGHCLs and scanning laser beams or microdisplays with laser based illumination. A microdisplay can be used or it can be replaced by a focused modulated scanning laser beam that paints a high-resolution real image on a diffuser. HMDs can be panchromatic (RGB) or monochromatic, where a single laser wavelength is input for monochrome and three-color (RGB) laser beams are input for panchromatic.

[0029] In one embodiment, a holographic substrate-guided head-mounted see-through display includes: (a) an image source comprising a focused, modulated, scanned laser beam that draws a real image on a diffuser or placed in the plane of the diffuser; Microdisplay with laser-based illumination in ; (b) edge-illuminated transparent substrate; and (c) single-volume reflective SGHCL. SGHCL is index matched to the substrate.

[0030] In another embodiment, a holographic substrate-guid...

Abstract

Holographic substrate guided head-mounted see-through displays and recording systems and smart glasses are described. The present application relates to a head-mounted see-through display using a recorded substrate-guided holographic continuous lens (SGHCL) and a scanning laser beam or micro-display with laser irradiation that produces images on a diffuser. The high diffraction efficiency of the volumetric SGHCL results in very high brightness of the virtual image.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to co-pending US Patent Application Serial No. 16 / 800,531, filed February 25, 2020, which is incorporated herein by reference. technical field [0003] The present application is directed to monochromatic or full-color head-mounted displays (HMDs) characterized by volumetric substrate-guided holographic reflective continuous lens (SGHCL) optics incorporating scanning laser beams or microdisplays with laser-based illumination. Background technique [0004] Combined sales of augmented reality (AR), virtual reality (VR) and smart glasses are estimated to hit nearly $80 billion in revenue by 2025. About half of the revenue is directly proportional to the hardware of the installation, with optics being the key. However, despite such great demand, such devices remain difficult to manufacture and lack quality. One reason is that conventional optics are limited to the laws of refraction and r...
