A practical system for translation of information coded on punched paper tape to a matrix on a photograph is presented. The information here consisted of stereo random brightness fields; however, the system should be applicable to any three-dimensional information. The matrix is developed by slow digital scan of an intensity (ten levels) modulated oscilloscope and is photographed by a camera on time exposure. The system requires 166 seconds to produce each 10 000 element matrix and hence cannot be used for on-line work. However, for the researcher who can tolerate this limitation, the system's low cost, simplicity, and good resolution (better than 100 elements per inch) should prove attractive.
