Abstract

Die Erfindung betrifft eine optoelektronische Vorrichtung (1) zur Ermittlung eines Schnittbildes einer Objektstruktur mit einem Sendelichtstrahlen (6) emittierenden Sender (7), einem Empfangslichtstrahlen (8) empfangenden Empfänger (9), welcher eine zeilenförmige Anordnung von N Empfangselementen (10) aufweist und einer Auswerteeinheit zur Auswertung der Ausgangssignale An (n = 1, ...N) der Empfangselemente (10). Die Objektstruktur ist von wenigstens einer Kante eines Bogens gebildet und wird mittels der Sendelichtstrahlen (6) beleuchtet. Die an der Objektstruktur zurückreflektierten Empfangslichstrahlen (8) generieren eine Abbildung der Objektstruktur auf den Empfangselementen (10) des Empfängers (9). Zur Ermittlung der Objektstruktur werden die Ausgangssignale An mit zwei Schwellwerten S1, S2 mit S2 ≥ S1 zur Unterscheidung von belichteten Empfangselementen (10) mit Ausgangssignalen An > S2 und unbelichteten Empfangselementen (10) mit Ausgangssignalen An < S1 bewertet.
