Abstract: The invention relates to a method and arrangement for short coherence holography for distance measurement, for profile detection and/or for 3D detection of one or more object elements and/or object areas and/or objects or for readout of holographic volume memories with a holographic interferometer and with at least one short coherence light source. For each optically detected object element in the hologram the holographic interferometer has an optical path difference clearly unequal to zero. At least one spectrally integrally detecting, rastered detector is arranged. The short coherence light source with frequency comb is designed with the optical delay length Y1. Detected holograms are digitally reconstructed. Relative distances of object elements are digitally calculated from the hologram reconstructions, so that a 3D point cloud of object elements and/or object areas and/or objects is produced. Data can be read out optically in parallelized form from holographic volume memories or three-dimensionally structured signatures.
