Near-eye display rigid frame binocular alignment

A method for alignment of images in a near-eye binocular display system, comprising:

• providing a substantially rigid binocular frame, operable to support two or more waveguides, wherein each said two or more waveguides comprise:
• an in-coupling diffractive optic operable to diffract image-bearing light beams from an image source into said waveguide, and
• an out-coupling diffractive optic operable to diffract said image-bearing light beams from said waveguide toward an eyebox;
• wherein said in-coupling diffractive optic is operable to in-couple light propagating along a first direction, and said out-coupling diffractive optic is operable to out-couple light in said first direction;
• positioning a first projector at a first side of said binocular frame to project a first image;
• projecting said first image upon a screen without said two or more waveguides supported by said binocular frame;
• positioning a second projector on a second side of said frame to project a second image;
• projecting said second image upon said screen without said two or more waveguides supported by said binocular frame;
• comparing said first image and said second image with respective targets;
• and
• adjusting said positioning of at least said first projector or said second projector to align said first image and said second image with said respective targets.
