Abstract
Disclosed is a random phase diffuser which is inserted between a transducer and an insonification subject in accoustical imaging. The diffuser is comprised of an array of lossless elements which cause sound emitted by the transducer to be passed through and emitted with a phase value of 0.degree. or 180.degree.. Additionally disclosed is the combination of a random phase diffuser with a wedge coupling feature for increasing insonification efficiency.
