Abstract :
A second order two-dimensional spatial image differentiation has been performed using an analogue self-electro-optic effect device (SEED). The device integrates a pair of quantum-well modulators with a set of five conventional photodiodes designed to extract local spatial differentiation. The result shows that this device is suitable for studying early vision processes
