Abstract:
An optical display comprises: a first waveguide comprising a first surface and a second surface, an input coupler, a fold grating, and an output grating. The input coupler receives collimated first wavelength light from an Input Image Node causes the light to travel within the first waveguide via total internal reflection between the first surface and the second surface to the fold grating. The fold grating provides pupil expansion in a first direction directs the light to the output grating via total internal reflection between the first surface and the second surface. The output grating provides pupil expansion in a second direction different than the first direction and causes the light to exit the first waveguide from the first surface or the second surface. At least one of the input coupler, fold grating and output grating is a rolled k-vector grating, and the fold grating is a dual interaction grating.

Claim (Index 1):
An optical display, comprising:\n a first waveguide having a first surface and a second surface; an input coupler; a fold grating; an output grating; and an input image node (IIN), wherein said input coupler is configured to receive collimated first wavelength image modulated light and to cause said light to travel within the first waveguide via total internal reflection between said first surface and said second surface to the fold grating, wherein said fold grating is configured to provide pupil expansion in a first direction and to direct said light to the output grating via total internal reflection between the first surface and the second surface, wherein said output grating is configured to provide pupil expansion in a second direction different than said first direction and to cause said light to exit said first waveguide from said first surface or said second surface, wherein at least one of said input coupler, said fold grating or said output grating is a rolled k-vector grating, and wherein said light undergoes a dual interaction with said fold grating.
