Abstract
A distance measuring method and a distance meter for a distance measurement according to the principle of a frequency-modulated continuous wave radar, wherein at least a part of a first laser radiation, which comprises a first frequency modulation defining a first modulation band, and at least a part of a second laser radiation, which comprises a second frequency modulation defining a second modulation band, are emitted as the first or as the second emission radiation, respectively, to a target. A parameter is determined, which is indicative of a frequency offset between the first and the second modulation band, and the parameter is taken into consideration during the determination of the at least one distance to the target to derive a frequency difference between the first frequency modulation and the second frequency modulation.
