METHODS FOR DESIGNING DIFFRACTION GRATING FOR AUGMENTED REALITY OR VIRTUAL REALITY DISPLAY AND DIFFRACTION GRATING FOR AUGMENTED REALITY OR VIRTUAL REALITY DISPLAY - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240019698 titled 'METHODS FOR DESIGNING DIFFRACTION GRATING FOR AUGMENTED REALITY OR VIRTUAL REALITY DISPLAY AND DIFFRACTION GRATING FOR AUGMENTED REALITY OR VIRTUAL REALITY DISPLAY
Simplified Explanation
The disclosed patent application describes a diffraction grating that can be used as an output element in a diffractive waveguide combiner for augmented reality or virtual reality displays. The grating consists of two rectangular arrays of optical structures arranged on a plane, with each array differing from the other in at least one characteristic or being offset from each other by a different factor. This configuration allows the grating to receive light from an input direction and couple different orders of the light in directions that are at angles to the input direction, ultimately directing the light towards a viewer.

Original Abstract Submitted
a diffraction grating is disclosed for use as an output element of a diffractive waveguide combiner for an augmented reality or virtual reality display. the grating includes an interleaved rectangular grating () comprising a first rectangular periodic array of optical structures () and a second rectangular periodic array of optical structures () arranged on the plane. the first array of optical structures () and the second array of optical structures () differ from one another in at least one characteristic or the first array of optical structures () are offset from the second array of optical structures () by a factor which is different to half the period of the first or second rectangular array, such that the first array of optical structures () and the second array of optical structures () are configured to receive light from an input direction and to couple orders of the light in directions that are at angles to the input direction and to couple out orders of the light towards a viewer.
