Abstract
(DE)
Die vorliegende Erfindung betrifft eine optoelektronische Messvorrichtung, die u.a. zur Bestimmung von Winkeln geeignet ist, umfassend mindestens eine Lichtquelle (7), einen ersten Schenkel (1), der eine Messeinrichtung (5/12) mit mindestens einer Durchgangsöffnung (6) aufweist und mindestens einen zweiten Schenkel (2), der einen lichtempfindlichen Sensor (10) aufweist, wobei der mindestens eine erste Schenkel (1) und der mindestens eine zweite Schenkel (2), vorzugsweise über eine Verbindungseinrichtung (3/18) miteinander verbunden, frei gegeneinander drehbar sind und die Lichtquelle (7), die Messeinrichtung (5/12) mit der Durchgangsöffnung (6) und der lichtempfindliche Sensor (10) so angeordnet sind, dass Licht ausgehend von der Lichtquelle (7) durch die Durchgangsöffnung (6) der Messeinrichtung (5/12) auf den lichtempfindlichen Sensor (10) fällt, sowie ein Verfahren zur Bestimmung von Winkel und Relativlagen unter Verwendung dieser Vorrichtung.
(EN)
The invention relates to an optoelectronic measurement device which, among other things, is suitable for determining angles and comprises at least one light source (7), a first part (1) presenting a measurement device (5/12) with at least one through hole (6) and at least one second part (2) having a light-sensitive sensor (10). The at least one first part (1) and the at least one second part (2) are preferably connected by means of a connecting element (3/18) and can be freely rotated in relation to each other. The light source (7), the measurement device (5/12) with the through hole (6) and the light-sensitive sensor (10) are positioned such that light emitted by the light source (7) passes through the through hole (6) of the measurement device (5/12) and strikes the light-sensitive sensor (10). The invention also relates to a method for determining angles and relative positions by means of the above device.
