Abstract
Abstract An information retrieval system for reading and displaying information contained on a photographic film, in which the combination of the reading and displaying functions is accomplished by using multiplexing techniques. A single light path transmits light in two directions to achieve perfect registration between the information read from the film and the information displayed from the film.
