<p>Stereo views of a scene are reflected by plano mirrors 16 and 18 onto a concave mirror 10. The plano mirrors 16 and 18 are positioned to cause the reflected light from the concave mirror 10 to converge on and across the optical axis 32. The concave mirror 10 focuses real images 24 in planar registration in front of the concave mirror 10 and on the optical axis 32. When viewed from beyond the real images 24 an observer sees a separate stereo view 12, 14 in each eye 26, 28 which combine to provide a 3-D picture.</p> |
