Abstract
The CCD image sensor addresses the problem of noise, due to background charge generated by Compton scattering of gamma rays. In applications, in which an imager must operate in a high-radiation environment, such background noise reduces the video signal/noise. This imager reduces the amount of charge collected from Compton events, while giving up very little sensitivity to photons in the visible/near IR.
