Abstract
The use of a comparator and counter associated, on-chip, with each photo-element of an array. Sensing each photo-element without discharging it and allowing each photo-element to accumulate a charge which is large relative to noise variations. These features result in a photo-detector with large signal-to-noise ratios.
