In order to make planigrams of a three-dimensional object, the object is irradiated from different directions in order to form a superposition image which consists of separate perspective images, Multiple imaging of the superposition image is realized by means of an imaging matrix, the individual perspective images being superposed in a zone which is situated behind the imaging matrix and in which, for example, a ground glass plate can be arbitrarily positioned for the imaging of layer images. During the superposition of the individual perspective images by means of the associated imaging elements of the imaging matrix, however, artefact images are caused by the transmission of perspective image, by inappropriare imaging elements. These artefact images are suppressed in that on each artefact image a correction perspective image, derived from a perspective image, is superposed via an additional imaging element in order to compensate for the artefact image.</p> |
