Abstract

During an optoelectronic measuring method, an emitting device sends a sequence of optical impulses during a measuring cycle. A receiving device is provided for receiving reflected signals from a target located in the beam path of the emitting device. Said receiving device amplifies received signals in a signal processing step. The signals are eventually converted and digitized, whereby the individual samples of a digitized received signal are filed in cells of an electronic memory and the samples of other digitized received signals are added in a cophasal manner in these memory cells or with a defined phase displacement with regard to the emitter impulse. The emitted impulse sequences are divided into a plurality of impulse packets or so called "bursts". These bursts are separated by impulse absorption. A received impulse assigned to a target is detected in an electronic computer by means of defined algorithms which are each from the discrete-time, digitized and added received signals of the impulse of every burst. In addition, a distance value is calculated in said electronic computer from the running time of this reconstructed received impulse with regard to a pertaining start impulse. At the end of a measuring cycle, a velocity value for a target is calculated, produced and/or displayed from the plurality of distance values and the assigned measuring times.
