Brillouin scattering-a new geophysical tool


The complete interpretation of seismic data in terms of the physics and chemistry of the Earth's interior involves an understanding of the effects of composition, crystal structure, pressure, and temperature on the elastic wave velocities, attenuation, and density. Conventional ultrasonic methods of determining the elastic constants of materials important in geophysics have been summarized in recent review articles by Simmons and Anderson and Lieberman . These methods use transducers that are bonded to the specimen and require that the sample be accurately shaped. The frequency of vibration of the sample, or the transit times of an elastic pulse, combined with an accurate measurement of length yield the elastic wave velocities.
