  • Distance measurement
    Patent number: 8705953
    Abstract: Provided in accordance with the invention is a method for measuring the distance of an object in which a transmitted signal (S) with a pulse train having a prescribed pulse repetition frequency (fw) is generated such that the transmitted signal has a frequency comb in the frequency domain, the transmitted signal is directed onto the object, and a reflected signal (R) reflected from the object is received, the phase difference (?MESS,1) between the transmitted signal and the reflected signal is determined for a prescribed spectral line of the frequency comb, and the distance is determined with the aid of the phase difference.
