Polarization anaglyphs. Polaroid company's ingenious method
1

During the Second World War,  aviators needed a portable means of identifying targets via stereoscopic film.  Polaroid Company of Cambridge MA developed a film process by the inventive executive Edwin Land.  Called the Vectograph, the Navy trained its photographer mates to develop and process the film.  Using two stereo images printed back to back on a special sheet and treated with a solution that gave the effect in different angles of polarization, they could be viewed by the then well known Polaroid filtered glasses.  Like those used at Worlds Fair Chrysler.   In school my pals and I experimented with this method.  Worked well. But costly and did not take off.  There were even some color Vectographs intended to become a single strip film for movie theaters.  A little remembered by way of stereo viewing.

An article from the period explaining the polarization anaglyph forms in stereo photogrammetry.
