摘要：
Acousto-optic imaging consists in tagging multi-scattered photon paths with a focused ultrasonic beam. This technique should give optical information on hidden structures in several centimeter thick scattering media, with a millimetric resolution. We have coupled our previous acousto-optic imaging setup with a suitably designed echograph. Thanks to a single 3 MHz multi-ring emitter, working either in pulsed or c.w. mode, we can get acoustic as well as acousto-optic responses of structures in biological tissues.
