Vibration measurement on the human ear drum in vivo

This paper describes the application of electronic speckle pattern interferometry to vibration measurements on the human ear drum in vivo. The technique makes use of a continuous wave laser, reference wave phase modulation, and videorecording of interferograms for subsequent analysis. Preliminary re...

Description
Summary:This paper describes the application of electronic speckle pattern interferometry to vibration measurements on the human ear drum in vivo. The technique makes use of a continuous wave laser, reference wave phase modulation, and videorecording of interferograms for subsequent analysis. Preliminary results, like frequency response and amplitude and phase measurements, are presented to illustrate the ability of this technique.
