Development of Open Mode Digital Radiographic Testing System

Abstract:-The open mode digital radiographic system based on the scintillation conversion screen and scientific grade CCD camera applies wide range radial energy and can be obtained high quality image. The composing and main technical requires are introduced. Author designs the structure of scintillation screen, the spectral characteristic of scintillation screen is introduced, CCD is chosen and its parameter characteristics are introduced, image data parallel acquisition scheme by remote computer are designed. The light route system is designed, the experimental result at low and high energy of X-ray of the system developed by author is given. Key-words:- open mode digital radiographic, X ray imaging, scientific grade CCD, enhance parallel port, spatial resolution; scintillation
