We present here a classical optics device based on an imaging architecture asanalogy of a quantum system where the violation of the Bell inequality can beevidenced. In our case, the two qbits entangled state needed to obtain nonclassical correlations is encoded using an electromagnetic wave modulated inamplitude and phase. Computational states are represented in a way where eachone of the two qbits is associated with two orthogonal directions in the inputplane. In addition, unitary operations involved in the measurement of theobservables are simulated with the use of a coherent optical processor. Theimages obtained in the output of the process, contain all the information aboutthe joint, marginal and conditional probabilities. By measuring the intensitydistribution in the image plane we evaluate the mean values of the simulatedobservables. The obtained experimental results show, in an illustrative manner,how some correlations of Clauser-Horne-Shimony-Holt type exceed the upper boundimposed by the local realism hypothesis as a consequence of the joint effect ofentanglement and two-particle interference.
