Non-linear and adaptive signal-processing device

A device for processing non-linear adaptive signals, comprising:

• an image source outputting an image signal to an optical valve, said optical valve including a means for producing and outputting coherent optical waves;
• an optical interconnection device receiving said output coherent optical waves from said optical valve wherein said optical interconnection device includes an optical filter wherein said optical filter includes a means for optically providing a Fourier plane of said image from said source and wherein said optical interconnection device provides an output;
• a non-linear, adaptive neuronal processor receiving the output of said optical interconnection device.
