Claim:
1. An opto-electronic distance measuring device comprising: a transmitting unit having a driver stage for a light source for emitting optical pulses as pulsed-mode-intensity-modulated optical radiation; a receiving unit for receiving a portion of the optical radiation, said portion being reflected from a target object, and converting it into an electrical reception signal by a photosensitive electrical component; an analogue-digital converter for digitizing the reception signal; and an electronic evaluation unit which is configured such that a distance from the target object can be ascertained on the basis of a signal propagation time using the digitized reception signal, wherein the driver stage is configured such that at least two pulse durations of different length for the optical pulses, a short pulse duration or a long pulse duration, are set, and wherein the short pulse duration is emitted for the distance from the transmitting unit to the target being closer and the long pulse duration is emitted for the distance from the transmitting unit to the target being further.
