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.

A compact virtual image electronic display system comprising:
- a microdisplay for producing a source object;
- a first magnification optic for providing a magnification function and a reflection function, the microdisplay and the first magnification optic each having a centerpoint defining a first optical axis, the first magnification optic magnifying the source object and reflecting a magnified virtual image, the center of the magnified virtual image defining a second optical axis, the second optical axis being at an angle .phi. relative to the first optical axis;
- a second magnification optic for providing a compound magnified virtual image of the magnified virtual image to an observer, the angle .phi. between the first and second optical axes being sufficiently small that the source object is within the full field of view provided by the second magnification optic;
- and
- a control mechanism for providing control signals to the microdisplay which modifies the source object produced by the microdisplay.
