Paper Abstract

A sensor by means of optical fiber bundle was developed for detecting microscopic displacement and vibration in tympanic membrane. Illuminating a planer object and detecting the reflected light with the bundle, we experimentally investigated the received optical intensity against the distance from the object. As a practical application to clinical examinations, we then measured the displacements and vibrations of tympanic membranes of a dog.
