Abstract
A display system may include a waveguide and an input coupling prism. The waveguide may have a lateral surface with a deformed region. The prism may couple the light into the waveguide at an angle whereby the light first reflects off the deformed region. The display module may include a display panel that provides the light with planar wavefronts. The display module may include a deformation mitigation structure that distorts the planar wavefronts to produce non-planar wavefronts. The shape of the non-planar wavefronts may be selected to reverse distortion to the wavefronts of the light produced by the first reflection of the light off the deformed region of the lateral surface. This may serve to mitigate distortion in the light produced by the deformed region of the lateral surface and may serve to maximize the sharpness images in the image light provided to an eye box.
