Patent: Holographic Display System
Publication Number: 20180364482
Publication Date: 2018-12-20
Applicants: Microsoft
Abstract
Examples are disclosed that relate to holographic display systems. One example provides a display system comprising a waveguide, a light source configured to introduce light into the waveguide at a controllable light input angle, and a holographic optical element (HOE) configured to outcouple from the waveguide light received from within the waveguide that meets an angular condition. The display system may further comprise a controller configured to control the light input angle and also to control a corrective component optically downstream of the HOE to correct for aberration of the light by the HOE based upon the light iput angle.
Background
A near-eye display, such as a head-mounted display device, may be used to present immersive visual experiences.
