Summary

[edit]
Description
Deutsch: Schärfetest anhand von einem Siemensstern, mit Beispiel zur Auswertung: Das Zusammenspiel von Optik und Sensorik kann über einen Siemensstern ermittelt werden. Die beiden linken Bilder zeigen das Auflösungsvermögen zur Bildmitte hin, mit Ausschnittsvergrößerung. In der Mitte des Siemenssterns entsteht ein unscharfer Fleck, der sogenannte Grauring. Über die Größe des Grauringes läßt sich die effektive Auflösung eines Testsystems berechnen. In der Beispielabbildung erzeugt Testsystem 1 einen größeren Grauring und ist daher in der effektiven Auflösung geringer als Testsystem 2.
