These binoculars were developed in Germany, originally to allow medical researchers to view 3-dimensional X-Ray images. As planned, their use at LLNL was to help the designers see three dimensional views of their work. This scheme was first tried before 1960. This device was one of several differing attempts to utilize three dimensional images in the analtsis of computer generated simulations. At LLNL we had a Xerox printer that could produce images on printout paper. If two consecutive images were suitably produced, and hung say on an easel, then by looking at them through the binoculars one could view the printouts as a single, fused three dimensional image. The instrument allowed the user to adjust the inter-pupilary angle, and the focus. Although the idea was simple, inexpensive and worked well, other techniques were preferred by the users.
