Das
konfokale Detektionsprinzip wurde 1961 von Marvin Minski im Patent
Die
gebräuchlichste Form eines auf Vielstrahlinterferenz basierenden
Filters ist das Fabry-Perot-Interferometer. In speziellen Ausführungen wird
es auch als Etalon bezeichnet und in vielen optischen Messgeräten
zur Wellenlängenselektion eingesetzt. So wird in der
Beschreibung der ErfindungDescription of the invention
Ziel der Erfindung ist die Miniaturisierung des notwendigen Bauraums robuster konfokaler Sensoren beispielsweise für die Topografiemessung in schwer zugänglichen Bohrungen.aim The invention is the miniaturization of the necessary installation space Robust confocal sensors, for example for topography measurement in hard-to-reach holes.
Im
Folgenden wird das erfindungsgemäße Detektionsverfahren
am Beispiel eines planen Etalons erläutert, ist aber mit
der gleichen Argumentation auf alle Vielstrahlinterferenz erzeugende
Objekte anwendbar. Ein Etalon (
