Abstract
Each imaging element (2a) of an array (2) includes a photosensitive element (3) for sensing light incident on the imaging element (2a) and for storing charge representing the incident light and a rectifying element (D1). The imaging elements (2a) are arranged in rows and columns with each photosensitive element (3) and the associated rectifying element (D1) being coupled in series between an associated first conductor (4) and an associated second conductor (5, 6) for allowing charge stored at a selected imaging element (2a) to be read out by applying voltages to the second conductors (5, 6) to forward bias the rectifying element (D1) of the selected imaging element to cause a current representing the charge stored at the photosensitive element (3) of the selected imaging (2a) element to flow through the associated first conductor (4). Each rectifying element (D1) is formed by a photosensitive element for also receiving light incident on the imaging element and the relative dimensions of each photosensitive element (3) and the associated rectifying element (D1) are such that when an imaging element (2a) is receiving light but is not selected any leakage current flows internally with…
