<p>A latent charge image is recorded on and reproduced from a multilayered detector (10) by first providing the detector (10) with a uniform surface charge on its photoconductive layer (16). The photoconductive layer (16) is then biased with an electric field whose polarity opposes that of the uniform surface charge and then the detector is exposed to a modulated radiation flux to cause at least partial discharge of the photoconductive layer (16). The latent charge image of the modulated radiation flux is thus stored and later read by scanning the surface of the photoconductive layer (16) with a small diameter photon beam to further sequentially discharge the photoconductive layer (16) and the changing electrical potential of this sequential further discharge is detected and processed into a video signal by a processor (106) for storage or display. </p> |
