Paper Abstract

This study deals with the simulation of the image formation involved by using a nonlinear image processor composed of a nonlinear medium placed at the common focus of a 4-f system. A simple linear model is developed taking into account the third-order optical nonlinearity of the medium and the optical transfer function f the 4-f system. The simulated images through the system are given for phase and/or amplitude rectangular objects. Our model and its corresponding simulation lead to optimize nonlinear parameters of the medium for this class of objects, whatever their transmittance is, in order to enhance the visibility in image processors.
