Abstract

Die Erfindung betrifft eine Vorrichtung zur Messung von Feuchtigkeit und Reflexionsvermögen von Oberflächen mit Hilfe von Licht. Aufgabe der Erfindung ist es, die Vorrichtung so auszugestalten, daß sie genaue Messungen auch bei schnell veränderlichem Abstand und schneller Bewegung des Meßojekts ermöglicht. Gelöst wird diese Aufgabe durch eine Beleuchtungsvorrichtung, deren Emissionsspektrum zwei Bereiche enthält, wobei der eine Bereich Teile einer Wasserabsorptionsbande und der andere Bereich einen benachbarten Teil davon umfaßt, einen Strahlteiler zur Aufteilung des Lichts in zwei Teilstrahlen zum Bestrahlen der Oberfläche in zwei Meßflächen, einen Spiegel, der den am Strahlteiler reflektierten Teilstrahl parallel zum durchgehenden Strahl umlenkt, und ein Nachweisgerät für den gleichzeitigen Nachweis der beiden Bereiche.
