ABSTRACT:
A method for forming a layered image of a three-dimensional object which is irradiated from different directions by a plurality of radiation sources. n coded superposition images, in different image planes, of a single movement phase are sequentially recorded on a mechanically moved detector face. Decoding of the n superposition images is realized by means of a coordinate matrix whose coordinates correspond to the geometry of the radiation source distribution, so that these images are successively electronically superposed and summed, for a number of times which equals the number of radiation sources. The same layer of the object is decoded n times and the n decoded layers are summed to form a layered image.
