Abstract

Here, we aim at imaging 3-D fluid objects concealed within a homogeneous fluid medium and illuminated by a time-harmonic source, from single-frequency multiview data. Two techniques are considered: (1) a diffraction tomography algorithm with Fourier domain interpolation, which provides qualitative images in a very efficient way; (2) a Newton-Kantorovich algorithm which builds up an iterative solution of a non-linear ill-posed inverse scattering problem, through a local linearization and a regularization procedure. Both synthetic and experimental data are considered.
