Original Abstract Submitted
the present disclosure relates to augmented reality devices and related methods. in one or more embodiments, an augmented reality device includes a projection system and a waveguide. the projection system includes a projector and a prism. the projector projects an image along the projectors major axis. the prism refracts the image having a first spectrum, a second spectrum, and a third spectrum. the waveguide is disposed at a wrap angle from a plane formed from the major axis of the projector. the waveguide includes an input coupler and an output coupler. the input coupler includes input structures at an input period and an input orientation and the input coupler is configured to receive the spectrums at different corresponding input angles. the output coupler includes output structures at an output period and an output orientation and the output coupler out couples the respective spectrums at an about equal output angle.
