Abstract
Application of the supercritical magnetoelastic wave phase conjugation to h armonic imaging in acoustic C-scan microscopy is demonstrated. Second-harmo nic generation by phase-conjugate wave is used for improvement of resolutio n of an imaging system. Possibility to compensate phase aberrations introdu ced in harmonic image by inhomogeneity of propagation medium is shown exper imentally and explained theoretically.
