Abstract:
An optical display, including a first waveguide having a first set of surfaces, an input grating, a fold grating, and an output grating; an image input image node assembly; and a prismatic relay optics is provided. The prismatic relay optics may be configured to be optomechanically connected to the waveguide and the input image node assembly. The optical display is may also be configured to operate alone or as integrated with a headpiece to be used as a HUD. The HUD may have a first and a second configuration wherein the waveguide is decoupled or coupled.

Claim (Index 1):
An optical display, comprising:\n a first waveguide having a first set of surfaces comprising a first open space disposed therebetween; at least one input grating disposed between the first set of surfaces and configured to receive an image from an Input Image Node assembly; at least one fold grating optically connected to the at least one input grating and disposed between the first set of surfaces; at least one output grating optically connected to the at least one fold grating and disposed between the first set of surfaces; a prismatic relay optics opto-mechanically disposed between the input image node assembly and the first waveguide; an opto-mechanical coupler disposed between the prismatic relay optics and the input image node assembly, wherein the first opto-mechanical coupler is configured to support the prismatic relay optics and receive a collimated first wavelength image modulated light and to cause the light to travel within the prismatic relay optics via total internal reflections to the first waveguide; and an optical interface coupler disposed between the prismatic relay optics and the first waveguide wherein the optical interface coupler is configured to receive the wavelength image modulated light as reflected within the prismatic relay optics and optically communicate said image to the first waveguide wherein the image will be reflected within the first waveguide via total internal reflection between said first set of surfaces from the at least one input grating 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 set of surfaces; and 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 set of surfaces.
