Paper Abstract

For the purpose of observing the vibration of the human tympanic membrane clinically, a holocamera was test designed and manufactured. At the stage of test design, an experiment revealed the deterioration of laser light in its coherency when it came out through the optical fiber. As the method of improving the deteriorated coherency, two laser beams both of which were passed through the optical fiber bundle, were used for the illumination beam as well as the reference beall under a certain condition. This procedure made possible to manufacture a pulsed holo-camera well suitable for the clinical use
