LASER DISTANCE MEASURING DEVICE

摘要

The invention relates to a laser distance measuring device, which has an emitting unit (10) with at least one laser and has a receiving unit (12) in addition to a single-sideband modulation unit (14), with which a modulation frequency (S1) of the emitting unit (10) can be generated from a first single-sideband modulation frequency (ZF1), which is generated by an oscillator unit (16), and from a carrier frequency (T1). According to the invention, at least one additional frequency (ZF2) can be generated by the oscillator unit (16), and a demodulation frequency (S2) of the receiving unit (12) can be generated from the additional frequency (ZF2) by the single-sideband modulation unit (14).
