  • DEVICE AND METHOD FOR COMPENSATING EFFECTS OF PANTOSCOPIC TILT OR WRAP/SWEEP TILT ON AN IMAGE PRESENTED ON AN AUGMENTED REALITY OR VIRTUAL REALITY DISPLAY
    Publication number: 20240094536
    Abstract: An optical device is disclosed for use in an augmented reality or virtual reality display, comprising a waveguide (12; 22; 32) and an input diffractive optical element (H0; H3; 34) positioned in or on the waveguide, configured to receive light from a projector and couple it into the waveguide so that it is captured within the waveguide under total internal reflection. The input diffractive optical element has an input grating vector (G0; Gig) in the plane of the waveguide.
