<p>In an imaging process and system by transillumination of a medium (H) illuminated by transparency by a beam (F1), an acoustic transducer (TA1) emits an acoustic wave in the medium (H) which interferes with the beam (F1). The frequency of the light passing through the medium (H) is then shifted from the value of the frequency of the acoustic wave. A collimating device (A) whose object focus is located at the intersection of the acoustic wave and the light beam (F1) collects the light diffused by the medium (H). Application: medical imaging.</p> |
