AI Technical Summary
Conventional augmented reality systems struggle to provide a comfortable, natural-feeling presentation of virtual image elements by accurately simulating depth, leading to issues like unstable imaging, eye strain, and headaches due to accommodation conflicts.
An augmented reality display system utilizing a diffractive optical element with a waveguide substrate and a surface grating, featuring a non-uniform underlayer with varying refractive index and thickness, and a switchable diffraction structure to manage focal planes and accommodate human visual perception.
Enhances the perception of depth by increasing the field of view, diffraction efficiency, and reducing eye strain, providing a more comfortable and stable 3D imaging experience.
