Abstract
In a dry silver photographic imaging device and method, two laser beams are generated. The laser beams are then modulated. One of the modulated laser beams is reflected and the other modulated laser beam is transmitted. The two beams are then swept across a dry silver film in order to form a desired image on the film.
