Abstract
A synthesized virtual image electronic display is provided that includes a microdisplay for forming a source object, a first magnification optic for magnifying the source object to produce a magnified real image, an image synthesizing optic upon which the magnified real image is projected, and a second magnification optic for providing a magnified virtual image of the magnified real image projected on the synthesizing optic. The image synthesizing optic is a diffractive element which provides the display of the present invention with significant optical and ergonomic advantages over that which can be achieved using prior art simple magnification and compound magnification systems.
