Abstract
An imaging scheme through scattering media in which parametric image a mplification is, used is presented. An image of a resolution chart thr ough a solution of latex microspheres with an attenuation of 22 mean f ree paths is obtained with a resolution of 20 mu m. The evolution of t he signal-to-noise ratio with respect to the medium attenuation is stu died and compared with a rough modeling of the imaging process. (C) 19 97 Optical Society of America.
