摘要:
A distance measuring method and an electronic laser distance measuring module, for determining a distance to a target object, wherein the transmitted signal is emitted with selected polarization states by a transmitting unit of the laser distance measuring module. The transmitted signal is emitted and the received signal is acquired such that a polarization identifier of the polarization state of the transmitted signal adheres to the received signal and an evaluation of the received signal is derived based on the polarization identifier, to take into consideration multiple reflections during the processing of the received signal to determine the distance.
