METHOD FOR DETERMINATION OF A DISTANCE AND DISTANCE MEASURING DEVICE WITH IMPROVEMENT OF THE EFFECTIVE RESOLUTION OF AN A/D CONVERTER BY PHASE MODULATION OF THE MEASURED SIGNAL

A distance measuring device and a method for determination of a distance uses an optical signal, with which an analog evaluation signal (36), with phase information, is digitized in an analog-to-digital converter (44), and the phase information is then evaluated in an arithmetic unit. The evaluation...

Zusammenfassung:A distance measuring device and a method for determination of a distance uses an optical signal, with which an analog evaluation signal (36), with phase information, is digitized in an analog-to-digital converter (44), and the phase information is then evaluated in an arithmetic unit. The evaluation signal (36) reaches the analog-to-digital converter (44) in phase-modulated form.
