| Abstract: | This paper points out the problems of CCD camera in energy distribution measurementfrom various aspects including the photo-elastic response non-uniformity and non-linearity in CCD sensor array; the scanning system conversion. the automatic gain control circuit and the γ correction circuitin camera. Solutions to each mentioned above are also discussed. In the meantime, the integral method to decrease noises is introduced. |
