Stereo Microscope Viewing through Computer Video

       This article describes a method and apparatus for
reproducing a stereo image produced by a stereo-microscope onto a
computer cathode ray tube (CRT) while maintaining a viewer's
perception of depth of the viewed object.

      A three-dimensional (3D) rendering is achieved in this article
by selectively displaying, right, and then left, eye-views from a
camera system, connected to the stereo-microscope.  These views are
then exposed to the appropriate eye, by selectively blocking the view
of the other eye, using glasses coated with liquid-crystal
(LC-glasses).

      The figure shows the viewing apparatus of this article.  At the
high-frame rate of the computer video, an image from the right-eye
camera is displayed in a window of the computer's CRT.  At the same
instant, the left-eye of the viewer is selectively blocked by
changing the left-eye of the LC-glasses opaque.  Because of this,
only the viewer's right-eye is exposed to the right-eye image from
the microscope.  At the start of the next video frame, the left-eye
image is displayed, and the right-eye of viewer is blocked by the
LC-glasses.  Directing only the proper camera image to viewer eye,
combined with the high-frame-rate presentation, will reproduce the
stereoscopic 3D image for the viewer.

      The stereo-microscope, with connected left-eye and right-eye
camera apparatus, a computer adapter for selectively displaying
images from ca...
