Reflection response Transmission response
Claerbout’s conjecture: ‘‘By crosscorrelating noise traces recorded at two locations on the surface, we can construct the wave field that would be recorded at one of the locations if there was a source at the other’’
Acoustic daylight imaging 1-Dimensional : 3-Dimensional :
Reflection response Transmission response
Assume uncorrelated noise sources: Claerbout’s conjecture
Seismic interferometry (Schuster) + ‘ other stuff ’
