Abstract
Abstract An optical image is presented in terms of visible light directed through contiguous light pipes to a Pockels effect plate disposed between a polarizer and an analyzer. Each of the light pipes is coated with a conducting metal so that each point on the Pockels effect plate can be controlled by a potential that is locally applied in such a way as to control transmissivity. In consequence, image information is applied to the assemblage by controlling the transmissivities of the various points independently.
