Abstract
We report an experiment of type 2 parametric image amplification in a phase sensitive configuration. In the spatial frequency domain, the parametric g ain corresponds to amplification or deamplification. depending on the relat ive phase of the input image with respect to the pump wave and on the spati al frequencies of the input image.
