Abstract
The invention relates to an electro-optical distance-measuring device, more particularly a laser rangefinder, with a transmitting unit for transmitting intensity-modulated optical radiation, a receiving unit for receiving a portion of the optical radiation reflected back from a target in a photosensitive electrical component and converting it into an electrical received signal, an input filter for filtering the received signal, an analog-to-digital converter for digitizing the filtered received signal and an electronic analysis unit that calculates the distance from the rangefinder to the target object on the basis of a signal propagation time using the digitized received signal. The input filter is implemented as a time-discrete and continuous-value filter structure, more particularly a digital filter structure.
