Abstract
Es wird eine optische Sonde (1) zum optischen Prüfen von Messobjekten vorgeschlagen, wobei diese umfasst: einen Eingang (10) zur Einführung eines Eingangsstrahls in die Sonde (1), mindestens ein optisches Element (8) zur Überführung des Eingangsstrahls in einen Messstrahl und mindestens einen Ausgang (20) zur Beleuchtung der zu prüfenden Messobjekte, wobei ein Mittel (15) zum Austauschen des mindestens einen optischen Elements (8) vorgesehen ist. Weiter wird eine Vorrichtung zur interferometrischen Messung von Messobjekten beschrieben, wobei in der Vorrichtung ein Interferometer mit der optischen Sonde (1) verbunden ist.The invention relates to an optical probe (1) for optically testing measuring objects, comprising: an input (10) for introducing an input beam into the probe (1), at least one optical element (8) for transferring the input beam into a measuring beam and at least one output (20) for illuminating the test objects to be tested, wherein a means (15) for exchanging the at least one optical element (8) is provided. Furthermore, a device for the interferometric measurement of measuring objects is described, wherein in the device an interferometer is connected to the optical probe (1).
Description
Stand der TechnikState of the art
Die Erfindung betrifft eine optische Sonde zum optischen Prüfen von Messobjekten gemäß dem Oberbegriff des Anspruchs 1 sowie eine Vorrichtung zur interferometrischen Messung von Messobjekten mit der Sonde.The The invention relates to an optical probe for optical inspection of DUTs according to the preamble of the claim 1 and a device for the interferometric measurement of measurement objects with the probe.
Es ist z. B. in der industriellen Fertigung von Bauteilen bekannt, die Bauteile während oder nach ihrem Herstellungsprozess optisch zu überprüfen. Dabei wird mit einer optischen Sonde die Oberflächen der Bauteile beleuchtet und ein verwertbares Bild von der Oberfläche gewonnen.It is z. B. in the industrial manufacturing of components, the components during or after their manufacturing process visually check. It is with an optical Probe illuminates the surfaces of the components and a usable image won from the surface.

Sollen jedoch mehrere Bauteile mit z. B. unterschiedlichen Bohrungsdurchmessern vermessen werden, ist ein Prüfen aller Bauteile mit einer einzigen, bisher beschriebenen Sonde nicht möglich, da weder die Fokuslänge der Sonde flexibel eingestellt werden kann noch das relevante optische Element einfach ausgetauscht werden kann. Die gleiche Problematik entsteht, wenn aufgrund der Form der Prüfkörper sehr viele verschiedene Austrittswinkel der Sonde notwendig werden.Should However, several components with z. B. different bore diameters is to test all components with one single, previously described probe not possible because neither the focal length of the probe can be flexibly adjusted still the relevant optical element can be easily exchanged can. The same problem arises when, due to the shape of the Test specimen very many different exit angles the probe become necessary.
