ABSTRACT:
The disclosed device and system enables the cell-based amplification of photo-e The disclop41 The detection device is realized by overlaying an amplifying semi-conductor structure, generally referred to as avalanche photo-diodes, on top of a typical prior-art charge coupled device structure. The disclosed arrangement is a hybrid of these two technologies with certain provisions which allow the two prior art technologies to function properly as a single integrated unit.
