This paper applies the multiple signal classification (MUSIC) imaging method to determine the locations of a collection of small anisotropic spherical scatterers in the framework of total internal reflection tomography. Multiple scattering between scatterers is considered, and the inverse scattering problem is nonlinear, which, however, is solved by the proposed fast analytical approach where no associated forward problem is iteratively evaluated. The paper also discusses the role of propagating and evanescent waves, the polarization of incidence waves, separation of scatterers from the surface of the substrate, and the level of noise on the resolution of imaging.
