Claim One:
1. A method of imaging a three-dimensional object with the aid of coding and decoding using coherent point codes, comprising recording the object with a plurality of radiation sources of different orientations on a recording medium, recording the object again separately with a second plurality of differently oriented radiation sources, forming the negatives of the two recorded images, separately combining the positive of each recorded image with the negative of the other image, to form two combined images, multiplying the combined images by means of point holograms formed with the aid of a reference wave and a multiplicity of light sources whose co-ordinates correspond to those of the point images of the two source arrays recorded by a pinhole camera, superimposing the two multiplied images in one plane, and decoding the coded images by changing their scale with the aid of two synchronously controlled zoom lenses whereby the co-ordinates of the point image function of an image of an object layer in the coded images are adapted to the points stored in the two point holograms.
