Abstract : Describes a system for increasing the relative sensitivity of a photographic system using dry silver emulsion film. Two concepts are combined to obtain the required sensitivity for dry film material. First an image intensifier tube is used to collect and amplify the light from the target to be photographed with the phosphor anode of the tube being coupled to the dry silver film by means of a fiber optics face plate. Secondly, photon amplification is additionally used to enhance the sensitivity of the dry silver emulsion, by illuminating the photo-cathode or the film itself at the time of exposure with a uniform low intensity non-imaging light.
