ABSTRACT:
An improved electro-optic modulator for a light valve device of the kind wherein the modulator is sandwiched between cross polarizer elements. The modulator includes a ferroelectric ceramic panel having a plurality of parallel grooves forming intervening parallel walled ridge portions. A series of address and reference electrode pairs are formed on the ridge side walls with each electrode pair being substantially parallel and opposingly centered on a normal across the intervening ridge portion. The electrode pairs of the series are staggered in location along respective ridge portions to define an array having a linear direction at about 45.degree. to the direction of the panel grooves. The panel can be oriented between the polarizer elements with the polarization directions of the elements parallel to and perpendicular to the linear direction of the array.
