Abstract

In this paper we present results of real-time imaging through biological tissues by means of nonlinear three-wave mixing phase conjugation process. Biological tissues with thicknesses up to 5 mm are used and the imaging process is performed at a near infrared wavelength included in the therapeutic window. Furthermore we show that real-time compensation of turbidity of biological tissues allowed with this method can be applied to scattering media in motion, with a significant improvement of the signal to noise ratio and resolution of the restored images.
