Abstract
In order to modify the characteristics of light which passes through a plate of electrooptical material such as PLZT ceramic, at least two conductive strips are arranged on each face in displaced relation to the strips on the other face and are connected on each face to different voltage sources. A diagonal electric field is produced between two opposite and relatively displaced strips, thus producing a considerable non-linear variation in transmitted light intensity according to the voltage applied.
