Patent

CA 2713652

The invention relates to an optical-electronic distance measuring method according to the phase measurement principle by emitting of optical measuring radiation, which is modulated according to the burst modulation principle, having a burst period duration made of an active burst time and a dead time, receiving at least a part of the measuring radiation (23), which is reflected on the measured object, wherein transforming into an input measuring signal (ES) is performed, and determining a distance to the measured object by analyzing a measuring signal (MS, gMS) generated from the input measuring signal

La présente invention concerne un procédé de mesure de distance optoélectronique, basé sur le principe de mesure de phase, consistant à : émettre un rayonnement de mesure optique modulé d'après le principe de modulation par salves - avec une durée de période de salve obtenue à partir d'une durée de salve active et d'un temps mort - en direction d'un objet de mesure; recevoir au moins une partie du rayonnement de mesure (23) réfléchi sur l'objet de mesure, cette partie du rayonnement de mesure étant convertie en un signal de mesure d'entrée (ES); et déterminer une distance par rapport à l'objet de mesure en évaluant un signal de mesure (MS, gMS) obtenu à partir du signal de mesure d'entrée (ES).
