摘要：

While several technical problems could be solved and the reproducibility of the technique appeared to be high enough, the individual variations between different persons seems to limit the importance of using laser Doppler vibrometry for clinical diagnosis. The complexity of the motions of the middle ear bones with frequency dependent superpositions of translational and rotational modes is seen as chance for a yield of information about middle ear diseases. A new concept is presented which relays on two laser beams guided under different angle onto the same spot to determine between the different kinds of motions. The theoretical and basis and first experimental tests are described to evaluate the reliability of this concept.
