We study the inverse problem of recovery a compactly supported non-linearity in the semilinear wave equation, in two and three dimensions. We probe the medium with complex-valued harmonic waves of wavelengthhand amplitude, then they propagate in the weakly non-linear regime; and measure the transmitted wave when it exits. We show that one can extract the Radon transform offrom the phase shift of such waves, and then one can recover. We also show that one can probe the medium with real-valued harmonic waves and obtain uniqueness for the linearized problem.
