| Abstract: | A method of developing X ray inspector based on scintillation screen and scientific grade CCD camera, which is can be applied to the case of high and low energy X ray imaging testing, is put forward. According to the demands of scientific work, the scintillation screen and scientific grade CCD are studied, the driving circuits and refrigeration circuits of CCD, and the quick data acquisition circuits for long distant as well as its software using the EPP mode of computer are designed. The whole instrument is developed and the experiments are done, the contrast and spacial resolution of developed inspector are higher than the type of digital radiography system based on X ray intensifier and video camera. |
