A breadboard experiment was performed which utilized a Bausch and Lomb Zoom 500 stereomicroscope, fabrications of an Expanded Exit Pupil EEP device and a High Intensity Light Source HILS. Experimental results showed it was possible to achieve a stereo image on the EEP screen that permits stereo viewing without the aid of supportive polorized glasses of anaglyphic differentiation. A projected stereo image was achieved throughout the Zoom 500 magnification range, however a significant reduction in the resolution of photographic inputs was measured. Brightness measurement showed that in all magnification used, a brightness exceeding 130-foot Lamberts was achieved. Unaided stereo viewing was possible within limits of head movement of or - 6 inches on axis and or - 1.5 inches off axis. Author
