An optoelectronic printhead having the configuration of optically and electrically controlled full-frame light valve was studied. The distinctive feature that sets our printhead apart from most conventional is that it is based on the neural network principles according to which massively parallel arrays of individually controlled pixels form the arrays of simple processing units. Supported digitally by soft and hard modeling of the adaptive self-learning neuron structures, such an “intellectual” light valve, allows executing of image processing operations in parallel mode until the image is ready for output.
