Unknowns in Multiple Scattering

C-29 UNKNOWNS IN MULTIPLE SCATTERING Summary K. VAN WIJK and J. A. SCALES Center for Wave Phenomena Colorado School of Mines Golden CO 80401 USA Multiple scattering of waves causes attenuation and anisotropic seismic velocities. In addition if scattering is strong enough energy propagation becomes diffusive. To study these effects we developed a medium in which the scattering properties can be easily controlled and the wave motion can be measured inside the scattering medium using an optical detection system. Introduction Multiple scattered waves are often regarded as a source of “noise” best removed from the data. Partly this is because
