ABSTRACT:
A method of coding and decoding of objects by means of a large number of point-like radiation sources which are subdivided into two groups. Two recordings are made of an image object. A first recorded image is made on a first recording medium with a first radiation source distribution. A second recorded image is made with a second radiation source distribution which is determined by the autocorrelation function of the first distribution. In the second radiation source distribution, the source which is determined by a function value in the origin of the autocorrelation function is omitted. In a first decoding step, the first recorded image is decoded with a point image function of the first radiation source distribution. In the second decoding step, the second recording is subtracted from the decoded first recorded image, so that an artifact-free image of the object is produced.
