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.
