Rectification of Imaging Device Defections in Real Time Radiographic Inspection

  • Received Date: 15 Aug 2001
  • Publish Date: 31 Jan 2003
  • Converter screen and CCD camera are the main imaging devices in real time radiographic inspection. Their defections are important factors affecting image quality. Based on experimental results, formation and characteristics of these defections were analyzed, a new mathematic model and a rectification method based on gray scale compensation were presented. It was indicated through experiments that this method is efficient in the rectification of the imaging device defections, with the least loss of useful information.
