Noninvasive Spectral Analysis and Beam Mapping of Focused Ultrasound. Part 1

Abstract

This is a report on the noninvasive analysis of ultrasonic fields where nonlinear distort initially sinusoidal sound fields, with the main emphasis being placed on the acousto-optic (schlieren) investigation of line- focused ultrasound propagating in water. Computational models and experimental results are presented as well as some results of phenomena related to reflection and transmission at boundaries of pulsed sound fields.
