Abstract
A method is described for the measurement of basilar membrane (BM) vibration. It makes use of commercially made laser Doppler velocimetry (LDV) instrumentation which is adapted to a compound microscope. This allows visualization reflective objects placed on the EM and the focusing of the laser beam onto the reflective object (a glass microbead). We show examples of frequency tuning curves and displacement input/output intensity functions obtained with the technique and demonstrate that cubic distortion of both the local and propagated kind are present in mechanical responses of the membrane.
