ABSTRACT:
In order to derive a distance to a target object, in the detection of lower and upper dynamic ranges different detection methods are used simultaneously for the same light signal in an opto-electric distance measuring method having at least one emission of at least one light signal onto a target object and one detection of the light signal scattered back by the target object, wherein the upper dynamic range is recorded by means of a threshold value method and the lower dynamic range is recorded by means of signal scanning for the identification and temporal positioning of the back-scattered light signal.
