Target-oriented imaging of acoustic media using unknown and uncontrolled random sources
Target-oriented imaging seeks to localize inhomogeneities within a medium from measurements of the waves that scatter off them. Conventionally, this requires both knowledge and control of the sources used to illuminate the scattering targets. In this thesis, I explore and develop methods for imaging arbitrarily complex acoustic scatterers that require neither knowledge nor control of the sources of illumination. Inspired by random-illumination imaging experiments in optics, I first provide a geometrical explanation of the memory effect, a phenomenon in which the interference of scattered waves ...
