Solid state imaging technique
First Claim
1. An optical imaging system comprisingat least one solid state element comprising an electrode, one or more dielectric regions, and one or more semiconductor regions each of which has the same conductivity type and one of which can be depleted of mobile charges, said solid state element further having a plurality of storage cell for storing an optical image as a charge in each of said plurality of storage cells;
- means for focusing an optical image on said solid state element, said optical image thereby being stored therein;
means which includes an integrating means for optically scanning said solid state element to read out said stored image so as to provide an electrical output which is linearly related to the total charge in each said storage cell and represents said stored image.

Abstract
An optical imaging system for use as a solid-state camera, for example, which includes a plurality of solid-state elements for providing long-term storage of images, such elements being, for example, MNOS chips having a plurality of storage cells, which chips when exposed to an image focussed thereon can store a representation thereof. The chips are at a later time optically addressed, as by a scanning-light beam, to read out the stored image so as to provide an electrical output representing the stored image, such output being usable to provide a visual representation of the image such as on a display screen or in hard copy form.
