Stereo image display using a concave mirror and two contiguous reflecting mirrors

摘要

Stereo views of a scene are reflected by plano mirrors onto a concave mirror. The plano mirrors are positioned to cause the reflected light from the concave mirror to converge on and cross the optical axis. The concave mirror focuses real images in planar registration in front of the concave mirror and on the optical axis. When viewed from beyond the real images an observer sees a separate stereo view in each eye which combine to provide a 3-D picture.
