Abstract
A method for holographic observation of sound sources and passive inhomogeneities in acoustic waveguides is proposed. The method is based on the principle of coherent phase conjugation. A possibility of visual observation of both sound sources and stationary inhomogeneities of different kinds is experimentally verified.
