Béla Julesz, “Binocular Depth Perception of Computer-Generated Patterns,” Bell System Technical Journal 39, no. 5, September 1960, page 1129: random-dot stereogram and displacement diagram. Published documentation following the 1959 development. Béla Julesz. Bell System Technical Journal, © 1960 American Telephone and Telegraph Company. Digitized issue: Bitsavers. Image source.

Julesz’s “Two Image Random Dot Stereograms” were 2 side-by-side randomly generated dot images. When viewed through a stereoscope they created the sensation of depth. Julesz displayed these patterns on a screen and developed the procedure at Bell Labs.
