Light guide with polarization separator for dual images

Abstract:

A beam separator has a composite prism having an external input face and an external output face co-planar to the input face. At least one polarization beam splitter surface is encased within the composite prism and has an edge that defines a boundary between the external input face and the external output face. A first reflective surface is disposed to redirect, along a direction orthogonal to the input face, light of a first polarization that reflects from the at least one polarization beam splitter.
