Abstract
Method for non-invasively characterizing a heterogeneous medium using ultrasound, comprising a step of generating a series of incident ultrasonic waves, a step of recording an experimental reflection matrix R(t) defined between the input emission basis (i) and an output reception basis (u), a step of determining a response REP(r,Δr) of the medium between an input virtual transducer (TV) calculated based on an input focusing of the experimental reflection matrix that creates an input focal spot around a first point (P), and an output virtual transducer (TV) calculated based on an output focusing of the experimental reflection matrix that creates an output focal spot around a second point (P), said response being expressed as a function of a central point (PC) of spatial position (r) in the medium located midway between the first and second points (P, P).
