Abstract
Method for ultrasonic characterization of a medium, comprising a step of generating a series of incident ultrasonic waves, a step of generating an experimental reflection matrix R(t) defined between the emission basis (i) as input and a reception basis (u) as output, a step of determining a focused reflection matrix RFoc(r, r, δt) of the medium between an input virtual transducer (TV) calculated based on a focusing as input to the experimental reflection matrix and an output virtual transducer (TV) calculated based on a focusing as output from the experimental reflection matrix, the responses of the output virtual transducer (TV) being obtained at a time instant that is shifted by an additional delay δt relative to a time instant of the responses of the input virtual transducer (TV).
