Abstract
An imaging plate comprising a first conductive layer having a plurality of conductive segments arranged thereabout, a photoconductive sandwich structure affixed to the first conductive layer, and a second conductive layer integrally affixed to the side of the photoconductive sandwich structure opposite the first conductive layer. The conductive segments of the first conductive layer are electrically connected to a conductor such that each of the conductive segments are selectively addressable. Each of the conductive segments is a conductive strip separated from adjacent conductive strips by dielectric material. The conductor is an accumulator bar extending across the conductive layer transverse to the conductive strips. A photoconductive bridge conects each of the conductive strips with the accumulator bar. The photoconductive bridge is a photoconductive dot. Each of the photoconductive dots is addressable by a properly positioned photon beam.
