Characterization and Scattering of Bounded Ultrasonic Beams.
Abstract
The papers deal with some aspects of ultrasonic beam properties, their mathematical representation, and theoretical predictions related to reflection and scattering. The first paper deals with an acoustic-optic method by which the frequency contents of a pulsed ultrasonic signal can be determined without the introduction of a transducer probe whose presence in the path of the signal might alter the composition or shape of the pulse. The second paper is concerned with reflection of an ultrasonic signal at a boundary, particularly with the recently mentioned possibilities of the existence of backscattering. The third article deals with a method of describing mathematically a bounded beam which is known not to have a Gaussian cross section, and with the reflected profile of such a non-Gaussian beam.
