Abstract: An artifact mitigation system includes a projector assembly, a set of imaging optics optically coupled to the projector assembly, and an eyepiece optically coupled to the set of imaging optics. The eyepiece includes an incoupling interface. The artifact mitigation system also includes an artifact prevention element disposed between the set of imaging optics and the eyepiece. The artifact prevention element includes a linear polarizer, a first quarter waveplate disposed adjacent the linear polarizer, and a color select component disposed adjacent the first quarter waveplate.

Abstract: Configurations are disclosed for presenting virtual reality and augmented reality experiences to users. The system may comprise a scanning device for scanning one or more frames of image data. The scanning device may be communicatively coupled to an image source to receive the image data. The system may further comprise a variable focus element (VFE) operatively coupled to the scanning device for focusing the one or more frames of image data on an intermediate image plane, wherein the intermediate image plane is aligned to one of a plurality of switchable screens. The plurality of switchable screens may spread light associated with the intermediate image plane to specific viewing distances. The system may also comprise viewing optics operatively coupled to the plurality of switchable screens to relay the one or more frames of image data.
