Abstract
A laser distance meter includes a laser light source configured to emit temporally modulated laser light toward target objects. The laser distance meter further includes a light detector configured to detect laser light reflected by target objects. The laser distance meter further includes a light detector configured to detect laser light reflects by target objects. The laser distance meter also includes an electronic control and analyzing unit configured to control the laser light source and configured to analyze signals of the light detector. The electronic control and analyzing unit is designed to drive the laser light source, detect laser light reflected by target object by directly synchronously sampling a reception signal over a measurement time duration, generating a detection signal for each modulation frequencies, carry out an inverse Fourier transformation of the detection signal, and evaluate the propagation time spectrum.
