Patent ID: 8705953

Claim:
A method for measuring the distance of an object, comprising the steps of: generating a transmitted signal (S) with a pulse train having prescribed pulse repetition frequency (fw) such that the transmitted signal has a frequency comb in the frequency domain, directing the transmitted signal onto the object, and a reflected signal (R) reflected from the object is received, wherein the phase difference (φ 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; wherein the phase difference (φ MESS,2 ) between the transmitted signal and the reflected signal is determined for a second spectral line of the frequency comb, and both the phase difference (φ MESS,1 ) between the transmitted signal and the reflected signal for the first spectral line, and the phase difference (φ MESS,2 ) between the transmitted signal and the reflected signal for the second spectral line are used in determining the distance.
