METHOD AND DEVICE FOR OPERATING A PMD SYSTEM

摘要

The invention relates to a method for controlling a PMD system which is characterized by controlling a photoelectronic mixing device (PMD) by at least one modulation signal (Umod) and one modulation signal (Umod) that is complementary thereto. A transmitter (E) emits electromagnetic radiation that is intensity-modulated by means of the at least one modulation signal (Umod). The inventive method is further characterized by varying the modulation signal (Umod) between at least two modulation frequencies (f1,f2,fi).
