Abstract
A near-eye display based on a polarization-selective diffusive combiner includes a polarizer for polarizing impinging ambient light to have a first polarization state, and a polarization-selective scatterer downstream of the polarizer, for passing through the ambient light having the first polarization state substantially without scattering, while scattering impinging display light having a second polarization state orthogonal to the first polarization state. The display light at the second polarization state may be provided by a projector, the polarization-selective scatterer playing the role of a projector screen. A polarization-selective ocular lens may be disposed downstream of the polarization-selective scatterer for viewing images generated by the projector while propagating through orthogonally polarized light from outside environment.
