Abstract: Laser Doppler Vibrometry is a well established technique to measure tiny motions without mechanical contact. Therefore this technique is suitable to detect the motions of the human hearing organ. For the clinical application of laser Doppler vibrometry different optical setups were used for the delivery system. The laser beam was guided by an optical fiber using the commercial output optic or a micro probe which had such a small diameter that it could be brought into the outer ear canal. The large number of successful measurements showed that laser Doppler vibrometry can be used in clinical routine. While the reproducibility of the method was seen to be sufficient, the variation from one person to another is seen as a critical point to apply this method for clinical diagnosis. The presentation will focus on the technical possibilities and limitations to improve the setup for a better clinical application.
