Abstract
A spatial two-dimensional Laplacian of an image is demonstrated using an analogue differential self-electro-optic effect device, integrated with an array of 3 x 3 detectors. The array was designed to generate z ero photocurrent if the power incident on it either is constant or has a linear dependence.
