1. A personal display device for displaying virtual images to a wearer, comprising:
a frame having a right temple section, a left temple section, a right eye see-through section, and a left eye see-through section;
a projection display device connected to the frame operable to project image-bearing light beams;
at least one waveguide stack module connected to the frame, the at least one waveguide stack module operable to propagate image-bearing light beams along a length of the at least one waveguide stack module, the at least one waveguide stack module being configured to receive the image-bearing light beams from the projection display device, the at least one waveguide stack module including:
an in-coupling diffractive optic formed along the at least one waveguide stack module operable to diffract at least a portion of the image-bearing light beams from the projection display device into the at least one waveguide stack module in an angularly encoded form;
an out-coupling diffractive optic spaced apart from the in-coupling diffractive optic along the length of the at least one waveguide stack module operable to diffract at least a portion of the image-bearing light beams from the at least one waveguide stack module in an angularly decoded form for viewing the image-bearing light beams from the projection display device; and
a waveguide housing having a waveguide-frame aligner operable to align the waveguide housing and the frame of the personal display device,
wherein the projection display device includes a projector-frame aligner aligning the projection display device and the frame of the personal display device, and
wherein the frame of the personal display device includes a projector-waveguide-frame aligner configured to align the waveguide-frame aligner and the projector-frame aligner to the frame of the personal display device.
