Optical phase conjugation in Nd:YVO4 for acousto-optic detection in scattering media

Résumé

Acousto-optic imaging is a technique that maps the optical properties of thick scattering sample with a millimetric resolution. The detection of the acousto-optic signal represents a challenge because it is very weak amongst a strong parasitic signal. Various methods based on holography in photorefractive crystals or digital holography have been studied. Here dynamic holography is obtained with the gain medium Nd:YVO4. We study the experimental feasibility of a detection system based on holography in a gain media and show the first acousto-optic results obtained in a 5mm slice of chicken breast.
