Abstract
A compact virtual image electronic display system is provided which includes a microdisplay for producing a source object. A first magnification optic magnifies the source object and reflects a magnified virtual image. A second magnification optic provides a compound magnified virtual image of the magnified virtual image to an observer. The source object is within the full field of view provided by the second magnification optic. A control mechanism provides control signals to the microdisplay which modify the source object produced by the microdisplay.
