Abstract

An imaging device for producing images from electron-hole producing radiation. Electron-hole pairs are produced in a radiation absorbing layer comprised of a photoconductive material. This layer covers an array of metal oxide semiconductor pixel circuits which are incorporated into and on a crystalline semiconductor substrate. Each pixel circuit has a charge collecting pixel electrode, a capacitor connected to the electrode to store the charges and a charge measuring transistor circuit. A voltage source provides an electric field across the radiation absorbing layer between the pixel electrodes and a radiation transparent surface electrode covering the radiation absorbing layer. A data acquisition system acquires and stores data derived from charge measurements and in a preferred embodiment a computer computes images from the data. The image may be displayed on a monitor or printed out on a printer. Preferred embodiments provide images from x-ray, ultraviolet and visible light.
