Visualization of multimode radiation patterns of acoustic transducers by acousto-optic diffraction
Abstract
Information concerning the spatial response of a wideband acoustic transducer when excited by a wideband signal is essential, specifically when the transducer exhibits extraneous modes within the bandwidth of both the transducer and the excitation signal. A method is presented by which the radiation patterns of these modes can be visualized discretely under short pulse excitation.
