摘要：
The invention relates to a method for measuring the distance of an object, wherein a transmission signal (S) having a pulse train with a predetermined pulse repetition frequency (fw) is generated, so that the transmission signal has a frequency comb in the frequency range, the transmission signal is directed at the object and a reflection signal (R) reflected by the object is received, the phase difference (
φ
MESS,1 ) between the transmission signal and the reflection signal is determined for a specified spectral line of the frequency comb, and the distance is determined from the phase difference.
