abstract = "Vibrations of the tympanic membrane (TM) play a key role for the transmission of sound to the inner ear. Today, there exist still problems in measuring the movement of the TM and there are unresolved issues in understanding the TM and its behavior. A non-invasive and contact-free in vivo investigation of the structure and the functional behavior of the TM would be a big step forward. In the presented study, the suitability of optical coherence tomography (OCT) for measuring the oscillation patterns of the TM in the frequency range covering the range of the human speech perception should be tested. For functional imaging a sound chirp was generated in the frequency range between 0.4 kHz - 6.4 kHz. To obtain the movement within a sufficient resolution, a grid of 25 x 25 measurement points was generated over the whole TM. The information of the oscillatory movement was encoded in the Doppler signal, provided by M-scans at several points of the TM. The frequency response functions of each frequency showed different oscillation patterns on the TM. The acquisition time of one single M-scan was only 8.5 ms and of the entire TM 5.3 s, emphasizing the potential of the method for future in vivo applications. Furthermore, the morphology was acquired with the same OCT-system, showing the feasibility for structural imaging and differentiation between typical regions of the TM. Thus, OCT was shown as a suitable method for the simultaneous measurement of the functional and structural behavior of the TM.",
