"Linear image differentiation by use of analog differential selfelectro optic
effect devices" Optics Letters, 19, 18821884 (1994). We demonstrate
onedimensional linear image differentiation, using an array of symmetric
selfelectrooptic effect devices with 64*32 elements. The device operates with pairs of
powersupply beams. The spatial derivative, which may be of either sign, is given as the
difference in the reflected output powers
