ABSTRACT:
A laser distance measuring device (1) includes a laser diode (4) for emitting a high frequency intensity modulated measurement light beam (3) and connected with a signal generating unit (SGU) that generates a high frequency measurement signal (9) for high frequency signal transfer, at least one receiver photodetector (8a) for receiving a measurement light beam (3) reflected from a measurement object (5) and connected to a high frequency demodulator (13) for generating a low frequency phase delay signal (S1) containing phase information of the reflected intensity modulated measurement light beam (3), and a microcontroller (μC) for calculating a distance (D) from the phase delay signal (S1) and connected to the high frequency demodulator (13), with the microcontroller (μC) being connected to a control photodetector (8c) arranged in the measurement light beam (3) for low frequency transfer for determining an interference modulation component.
