Abstract

A compact virtual image electronic display system including a beamsplitting magnification optic on which a source object is projected, the beamsplitting magnification optic having a refractive surface and a partially reflective surface for magnifying and reflecting the source object as a magnified virtual image, and a reflective element positioned for receiving and reflecting the magnified virtual image back to the beamsplitting magnification optic. The beamsplitting magnification optic receives the reflected magnified virtual image and magnifies and transmits it through the beamsplitting magnification optic as a compound magnified image of the magnified virtual image to an observer. In this display system, the beamsplitting magnification optic and reflective element are positioned such that the source object is projected on the beamsplitting magnification optic at least partially within an area of the beamsplitting magnification optic on which the reflected magnified virtual image is received by the beamsplitting magnification optic.
