Abstract
We describe an optical technique for measurement of mechanical vibrations in the auditory organs of living animals. The technique uses light scattered from the vibrating structure and offers several new advantages. Better than 1 angstrom sensitivity, 10 micrometers spatial resolution, and > 70 decibels dynamic range are achieved. Illustrative measurements of the mechanical response of the tympanic membrane of crickets (Gryllidae) are reported.Keywords
