A page-sized flat-plate image sensor array intended for use as a contact imager for documents is described. The imaging device is a matrix-addressed pixel array of light sensors fabricated from hydrogenated amorphous silicon on a glass substrate, with each pixel comprising an n-i-p sensor and a thin film switching transistor. The array requires no imaging optics and therefore collects light very efficiently, making it well suited to high speed document input or for medical X-ray imaging. The array fabrication, drive electronics, imaging properties, and applications are discussed, and some examples of images are presented.
