Distance Measuring Device, Measuring System and Method for Optical Distance Measurement

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a contactless optical distance measurement device and method. It works by modulating a light beam that is directed at a target object, then analyzing the phase of the reflected light to calculate the distance to the object. A light guide can be used to direct the modulated light to or from hard-to-reach measurement positions.

Patent Abstract

Die Erfindung betrifft eine berührungslose optische Abstandsmessung. Hierzu erfolgt eine Modulation eines Lichtstrahls, der in Richtung eines Zielobjektes ausgesendet wird. Durch Auswerten des Phasengangs des an dem Zielobjekt reflektierten modulierten Lichtes kann der Abstand zu dem Zielobjekt berechnet werden. Das modulierte Licht kann mittels eines Lichtleiters zu einer geeigneten Position geführt werden, von welcher der Abstand zu dem Zielobjekt ermittelt werden soll.
