Abstract
There is disclosed an apparatus and method for providing electrical signals representative of an image projected thereon. The apparatus includes an array of spaced apart, light sensitive elements formed from deposited semiconductor material and arranged for receiving said image. The elements are capable of effecting a detectable electrical characteristic responsive to the intensity of light received thereon from the image. The apparatus further includes isolation means for enabling the selective detection of the electrical characteristic of each element.
