Abstract

An optoelectronic system for measuring vibrational amplitudes below one micron has been developed. It was used to determine the microvibrational characteristics of the ossicles elicited by a prototype stimulator of an implantable middle ear hearing aid and the vibrational amplitude of a piezo-minifilm or silicon minidiaphragm of an implantable microphone design. Using a laser as light source a resolution of .005 micron was reached. Practical design using commercially available devices are surveyed.
