Abstract: A distance measuring method and device, wherein a first and a second laser radiation are generated so that the first laser radiation has a first frequency modulation and the second laser radiation has a second frequency modulation, wherein at least in sections a time derivative of the first frequency modulation is different from a time derivative of the second frequency modulation. In accordance with the invention the first and the second laser radiation are generated by modulating a base radiation by means of an electro-optical modulator, so that an output radiation comprising a carrier component and a plurality of sideband components is produced, wherein a first sideband component provides the first laser radiation and a second sideband component provides the second laser radiation.

Abstract: In a method for generating a synthetic wavelength, particularly for an interferometric distance measuring setup, with a primary laser source defining a primary frequency ?0 and at least a first sideband frequency ?1 of the primary frequency ?0, laser radiation with the first sideband frequency ?1 and a corresponding first wavelength is provided wherein the first sideband frequency ?1 is continuously shifted, particularly by modulating the primary laser source. The synthetic wavelength is generated by combining the first wavelength and a second wavelength which is defined by the primary laser source, particularly by superposition.
