Beschreibung
Zusammenfassung:	An optoelectronic device for distance measurement in a detection zone using a phase based time of light method is provided that has a transmitter device for transmitting a light signal that is modulated by at least one first modulation frequency f1, a reception device having at least one light reception element for generating a received signal from the light signal reflected back in the detection zone, and a control and evaluation unit that is configured to determine a phase offset between the transmitted light signal and the light signal reflected back and to determine a time of flight therefrom, and to evaluate a first amplitude determined from the received signal to determine an erroneous measurement by reflection of the light signal at an object in the detection zone outside an unambiguity range of the phase based time of light method.
