Abstract
A new electro‐optic light valve, based on the Pockels effect in a KD2PO4 crystal addressed by photoconduction, is described. At the present stage, the picture exhibits a resolution of 20 lp/mm (line pairs/mm), a very uniform contrast of 40/1, and an extensive grey scale; the writing time is less than 10 μsec. The device allows image addition and image subtraction and can be used as an input device in optical coherent processors.Keywords
