摘要：

An interferometric optical heterodyne method is developed for vibrational amplitude and phase measurements on auditory organs of live animals. Laser light diffusely scattered from the vibrating structure is used for the measurement. Vibrational amplitudes from less than 0. 1 A to above 400 A have been detected.
