OPTICAL STRUCTURE FOR AUGMENTED REALITY DISPLAY - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18344696 Titled 'OPTICAL STRUCTURE FOR AUGMENTED REALITY DISPLAY'
Simplified Explanation
This abstract describes an augmented reality display that uses a color projector to emit an image in red, green, and blue. The projected light passes through a pair of waveguides. The first waveguide receives the light and separates the different colors, coupling the red and green wavelengths into the waveguide and directing the green and blue wavelengths towards the second waveguide. The second waveguide then receives the green and blue wavelengths and couples them into the waveguide.
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 .
