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 input angle.
