This dissertation contains three main parts. Part one offers a general introduction to the mechanics of hearing and positions the current work within the state-of-the-art. The second part introduces a new method for optical tomography of macroscopic biomedical objects, which makes it possible to measure the three-dimensional geometry of the middle ear ossicles and the soft tissues connecting and suspending them. On top of high-resolution morphological models of the middle ear structures, we applied the technique in other fields of research as well. The third part deals with the development of a new optical profilometry technique which allows to measure deformations of the eardrum and other membranes or objects. This measurement method is initially developed to determine the elasticity parameters of the eardrum in-situ. At the end, I state our future plans with the techniques.
