A method for the layer-by-layer representation of three-dimensional objects by means of the coded images simultaneously - by means of position of the bore-hole

摘要

A method of layer-wise reproduction of three-dimensional images by way of a number of simultaneously recorded, encoded superposition images of different image planes. The object is irradiated from different directions. Simultaneous-superposition images of the object are recorded in encoded form, by means of a large number of m sources, from different directions in a number of n planes which are situated one below the other. The decoding of these images for the layer-wise reproduction of the three-dimensional object is effected so that for each individual layer each of the n simultaneous-superposition images, whose scale has been adapted relative to each other, is simultaneously or consecutively shifted and summed on a single recording medium a number of times which corresponds to the number of m sources during the recording of the object.
