Development of an Inverse Ultrasonic Radiative Transfer Technique

Abstract

The focus of this research is the development of an inverse ultrasonic radiative transfer technique for materials characterization. The technique characterizes multiple scattering materials by estimating the way a typical scatterer redirects ultrasonic intensity into new directions. The way in which a scatterer redistributes ultrasonic intensity is described by the shape of its phase function. The developed technique relies on the gathering of backscattered ultrasonic intensity for the purpose of determining the Legendre coefficients of the phase function. This determination is achieved through an approximate inverse solution of the radiative transfer equation (RTE).
