ABSTRACT:
A high resolution radiation sensitive imager includes a radiation sensitive photoconductive target for forming an image in response to incident radiation, a light sensitive cathode arranged in spaced apart relationship with the target, and an addressable light source coupled to the photocathode for causing the photocathode to emit electrons at localized sites for reading an image on the target.
