Abstract
The invention relates to a receiving unit for light-based measurements/surveying using an analog-to-digital converter for the clocked analog-to-digital conversion of light detection signals and a clocking means for clocking the analog-to-digital converter. According to the invention, the clocking means has, for receiving modulated light signals, a phase-locked loop having an input for light detection signals modulated according to the light signal modulation and an output for outputting a frequency multiple of the detected modulation frequency for the analog-to-digital converter clocking.
