Abstract
The invention relates to an electro-optical distance measuring device comprising a transmitting unit comprising a light source for emitting intensity-modulated optical radiation, a receiving unit for receiving a portion of the optical radiation, said portion being reflected from a target object, by means of a photosensitive electrical component and for converting it into an electrical reception signal. Furthermore comprising a conditioning unit for conditioning the reception signal comprising at least one amplifier stage, an analog-to-digital converter fox digitizing the conditioned reception signal, and an electronic evaluation unit, which is designed in such a way that a distance from the distance measuring device to the target object, can be determined on the basis of a signal propagation time with the aid of the digitized reception signal. According to the invention, in this case the amplifier stage is designed in such a way that it has a non-linear input-output characteristic.
