ABSTRACT:
A compact virtual image electronic display system is provided which includes a microdisplay for producing a source object, one or more magnification optics, and a distance adjusting mechanism for adjusting a distance between the one or more magnification optics and each other or a reflective surface, the magnification of the compound magnified image relative to the source object being dependent on this distance. The system may include a distance sensing mechanism for sensing the distance between the beamsplitting magnification optic and the reflective element and communicating the distance to a control mechanism which modifies the source object in response. The system can also include a control mechanism for causing the distance adjusting mechanism to adjust the distance in response to the source object produced by the microdisplay. The system can also include a user selectable input for modifying the source object.
