  "textContent": "A method for extracting geodetic/geodesic distance/ranging information with a signal generator for generating at least two HF modulation frequencies in the MHz- up to the GHz-range requires a system with a system-input, an optical radiation source, at least one target object (3a, 3b) and a receiver (4'') with a system output and an analysis/evaluating electronics. Initially, the system is excited with at least two, especially synthetic, modulation frequencies, preferably a group of discrete modulation frequencies, by applying at least one excitation signal at the system input. At least one system response is picked up at the system output and distance /ranging information is derived from the signal shape of the system response by the analysis electronics. Independent claims are included for (a) a device for carrying out the method, for (b) a geodetic/geodesic measurement instrument, especially a theodolite, for (c) a scanner for three-dimensional image-scanning and for (d) use of the device.",
