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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
