There had been an article in the 'Amateur Scientist' section of 'Scientific
American', back in the 60's, which had to do with projecting orthogonally
polarized light through a fish tank, and while wearing the appropriate
glasses, being able to see a 3D projection of the fish's turbulence while it
swam. They credited Schulman with the idea. Schulman has a patent for
putting polarizers in a microscope's condenser (which projects the light
through the specimen), matching them at the oculars, and getting... single
lens stereo! I took his idea and moved the polarizers to the objective for
my patent(s).
