Apparatus and method useful for recording high resolution images of radiation, such as from X-ray or gamma ray-emitting objects, comprising the use of an entrance plate having a number of randomly distributed pinholes which pass the impinging rays from the radiating objects, casting a number of overlapping images of the pinhole pattern on a sensing plate, which may be in the form of a photographic film, spark chamber or other readout or recording means. A comparison of the pinhole pattern with the overlapping image pattern by evaluating their convolution integral, which may be accomplished by one or more optical methods, such as passing radiation through the two patterns as they are successively shifted with respect to each other, or digitally on a computer will provide a high resolution reconstruction of the pattern of the radiation sources in the object field.
