Patent abstract
This document describes various apparatuses embodying, and techniques for implementing, a virtual image device. The virtual image device includes a projector and a lens configured to generate a virtual image as well as two diffraction gratings, substantially orthogonally-oriented to each other, that act to increase a field-of-view of the virtual image. The virtual image device can be implemented as a pair of eyeglasses and controlled to generate the virtual image in front of lenses of the eyeglasses so that a wearer of the eyeglasses, looking through the lenses of the eyeglasses, sees the virtual image.
