Summary
Speckle interferometry is a non-destructive measurement technique using a laser. The principles of the method are described. Human hyoid bones.(n = 10) were investigated. Loads were applied to individual points on the anterior surface of the body of hyoid bones. All hyoid bones showed an asymmetric displacement. The displacement was greatest in a plane vertical to the load. An evaluation of fracture behavior is possible due to the displacement pattern.
Zusammenfassung
Die Speckle-Interferometrie ist eine zerstörungsfreie laseroptische Meßmethode. Das Prinzip der Methode wird dargestellt. 10 menschliche Zungenbeine wurden untersucht. Die Kraft wurde von vorn punktförmig auf den Zungenbeinkörper geleitet. Alle Zungenbeine zeigten eine asymmetrische Auslenkung, in Richtung senkrecht zur Belastung war sie am größten. Aufgrund des Bewegungsmusters ist eine Aussage über das Frakturverhalten möglich.
