摘要
Waveforms obtained by correlation of diffuse fields are now widely used to estimate times of flight and ballistic Green's functions. Theory, however, predicts that such passively obtained waveforms should equal the full Green function of a medium, and thereby convey information on the details of a structure and the presence of isolated scatterers. Here we investigate diffuse field correlations in a reverberant elastic body and demonstrate that their shear and Rayleigh waves allow us to image internal and surface features. Resolution in the resulting images is comparable to standard medical and seismic images. (c) 2006 Acoustical Society of America.
