Paper Abstract

Laser-Doppler-vibrometry is used successfully to detect the motions of the tympanic membrane under normal hearing conditions. For more detailed information about the dynamical behavior of the middle ear, it is necessary to improve the experimental signal-to- noise-ratio, which is mainly determined by the amount of light coupled back into the interferometer. The paper focuses onto two possibilities to yield of this amount light by increasing the solid angle of the optics and increasing the reflectivity of the tympanic membrane.
