Comparison of Interferometry Techniques of Identification of Structures of Solid Media

This work presents a comparison between cross-correlation, crosscoherency and deconvolution in order to visualize their interrelations and possible performance under different circumstances of usage. Each interferometry method possesses its very own advantage. For example, although cross-correlation does not eliminate the source signature, it has the best performance for noisy signals. When arriving times are of primary importance, crosscoherence presents advantages as it is more precise though disregards the spectral amplitude.
