The present invention relates to a laser range finder.
There are known laser range finders, which have a transmitter unit with a laser, a receiver unit, and a single sideband modulation unit. In these laser range finders, the single sideband modulation unit can use a single sideband modulation frequency generated by an oscillator unit, which simultaneously corresponds to a low frequency or a useful signal for phase determination, and a carrier frequency to generate a modulation frequency of the transmitter unit.
The original carrier frequency is used as a demodulation frequency of the receiver unit.
