Abstract
A conjugate optics projection display system includes a beam splitter positioned for viewing an object through the beam splitter and a projector positioned to project an image through the beam splitter, where the projector has a focal plane distance. A retroreflector is optically coupled to the beam splitter and positioned at a distance from the projector, where the distance is less than the focal plane distance of the projector. The retroreflector may include retroreflective elements having a size effective to match or exceed optical resolution requirements of the display system.
