Abstract: Augmented reality glasses include near eye displays the include sources of imagewise amplitude modulated light optical coupled to spatial phase modulators or active zone plate modulators and optically coupled to eye coupling optics. The sources of imagewise amplitude modulated light can include emissive 2D display panels or light sources coupled to imagewise amplitude modulators. The eye coupling optics can include volume holographic diffraction gratings.

Abstract: Embodiments provide a camera design (e.g., an eyeball camera) that mimics a human eye in geometry, optical performance and/or motion. The eyeball camera adopts the same cornea and pupil geometry from the human eye, and has the iris and pupil configured with multiple texture, color or diameter options. The resolution of the eyeball camera is designed to match the acuity of typical 20/20 human vision, and focus is adjusted from 0 to 4 diopters. A pair of eyeball cameras are mounted independently on two hexapods to simulate the human eye gaze and vergence. The perceived virtual and real world are calibrated and evaluated based on eye conditions like pupil location and gaze using the eyeball cameras. The eyeball camera serves as a bridge to combine the data from spatial computing like eye tracking, 3D geometry of the digital world, display color accuracy/uniformity, and display optical quality (sharpness, contrast, etc.).
