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.

Figure 00000001
The invention relates to an optoelectronic device (1) for determining a sectional image of an object structure with a transmitter (7) emitting light rays (6), a receiver (9) receiving light rays (8), which has a line-shaped arrangement of N receiving elements (10) and an evaluation unit for evaluating the output signals A n (n = 1, ... N) of the receiving elements (10). The object structure is formed by at least one edge of an arc and is illuminated by means of the transmitted light beams (6). The received light rays (8) reflected back on the object structure generate an image of the object structure on the receiving elements (10) of the receiver (9). To determine the object structure, the output signals A n with two threshold values S 1 , S 2 with S 2 S S 1 are used to distinguish between exposed receiving elements (10) with output signals A n > S 2 and unexposed receiving elements (10) with output signals A n <S 1 rated.
