摘要： A method of operating a photodetector system. The method impresses a surface charge on a photon detector by establishing an electric potential across the detector, storing the detector in the dark, disconnecting the source of electric potential, and electrically connecting layers in the detector.

摘要： A method of recording and reading out a latent image which comprises placing a uniform surface charge on the photoconductive layer of a multilayered detector apparatus, biasing said photoconductive layer with an electric field whose polarity opposes said surface charge, discharging some portion of said surface charge of said photoconductive layer by exposing said detector to a modulated radiation flux capable of generating electron hole pairs in the photoconductor; scanning the surface of said partially discharged photoconductive layer with a small diameter photon beam whereby said surface charge is sequentially further discharged, and measuring the changing electric current of said sequential further discharge as a function of time.

摘要： Radiation is partially blocked by a pointlike absorber to establish a patterned flux whose intensity distribution is a function of source geometry. The flux strikes a receptor having a proper contrast to spatial frequency characteristic to map an image that is topologically equivalent to the source at an acceptable level of contrast and acuity.Apparatus is disclosed that is capable of practicing the invention in the X-ray and light regions of the electromagnetic spectrum.
