Electrooptical distance measuring device and distance measuring method

Abstract

Some embodiments of the invention relate to an electrooptical distance measuring device comprising light source, reception circuit comprising detector, in particular avalanche photodiode APD and control and evaluation component for deriving a distance to the target object. Some embodiments of the invention, the detector has at least two mutually independent reception segments for mutually independently generating a respective resultant electrical signal, wherein the reception segments are assigned to predefined or predefinable, in particular different, distance ranges to be measured. Furthermore, at least two independent amplifiers may be provided in the reception circuit. Some embodiments of the invention, therefore, for a reception segment which is assigned only to a lower distance range of comparatively near distances, an amplifier having a comparatively low gain factor can now be connected downstream, such that it is therefore possible as a result to avoid e.g. a rapid supersaturation even in the case of near distances.
