Abstract
In this paper, basic principles of in- and anti-phased array in the localization of a heterogeneity in a scattering continuum are discussed. Various geometric configuration of multi-source placements, initial phase, and sinusoidal ac amplitude modulation are introduced. Phase and light intensity profiles in the plane of interest were computed analytically for a homogeneous scattering medium. Changes in the phase and the ac intensity with respect to the position of absorbers were also simulated by using a probabilistic numerical solution, the B-W-K technique.
