摘要 |
<p>PCT No. PCT/FR88/00356 Sec. 371 Date Feb. 27, 1990 Sec. 102(e) Date Feb. 27, 1990 PCT Filed Jul. 1, 1988 PCT Pub. No. WO89/00278 PCT Pub. Date Jan. 12, 1989.In an imaging process and system by transillumination of a medium illuminated by transparency by a beam, an acoustic transducer emits an acoustic wave in the medium which interferes with the beam. The frequency of the light passing through the medium is then shifted from the value of the frequency of the acoustic wave. A collimating device whose object focus is located at the intersection of the acoustic wave and the light beam collects the light diffused by the medium.</p> |
