Abstract

Die Erfindung betrifft einen optischen Sensor (5) zum Vermessen von Profilen nach dem Prinzip des Lichtschnittverfahrens, der folgendes umfasst: mindestens einen Linienprojektor (6), der eine Lichtlinie (9) auf ein Messobjekt (8) ausstrahlt, dessen Profil zu vermessen ist; und mindestens zwei Bildaufnahmeelemente (7, 7') mit einem jeweiligen Sensorelement (2, 2') und einer jeweiligen Objektivanordnung (19, 19') zur Erfassung des reflektierten Strahls des Messobjekts (8), wobei die Bildaufhahmeelemente (7, 7') unterschiedliche Brennweiten haben, wobei jedes Sensorelement (2, 2') nicht parallel zur Ebene der Objektivanordnung (19, 19') angebracht ist.
