This abstract first appeared for US patent application 20250076660 titled 'OPTICAL STRUCTURE FOR AUGMENTED REALITY DISPLAY

==Original Abstract Submitted==

an augmented reality display is disclosed. a colour projector  emits an image in a narrow beam comprising three primary colours: red, green and blue. a pair of waveguides  is provided in the path of the projected beam. a first input grating  receives light from the projector  and diffracts the received light so that diffracted wavelengths of the light in first and second primary colours are coupled into the first waveguide , and so that diffracted wavelengths of the light in second and third primary colours are coupled out of the first waveguide in a direction towards the second waveguide . a second input diffraction grating  receives light coupled out of the first waveguide  and diffracts the second and third primary colours so that they are coupled into the second waveguide
