ABSTRACT:
A compact, virtual image electronic display system is provided for forming a compound magnified virtual image of a source object. The display system includes a microdisplay for producing the source object, a first reflective magnification optic, and a second magnification optic which, in combination with the first magnification optic, forms a compound magnified virtual image. The first and second magnification optics may be separate optics. Alternatively, a single beamsplitting magnification optic may be used as both the first and second magnification optic. When a single beamsplitting magnification optic is employed, the beamsplitting magnification optic serves as both a first, reflective magnification optic to produce a magnified virtual image and as a second, transmissive magnification optic to produce a compound magnified virtual image which is seen by the observer. By using the same optic in a reflective mode as the first magnification optic and in a transmissive mode as the second magnification optic, any aberrations introduced into the image during the first stage of magnification are substantially removed during the second stage of magnification. As a result, the compound magnified virtual image produced is substantially aberration free.
