Design of X-ray Digital Imaging and Data Acquisition System1

摘要

X-ray digital imaging technology is a new method of nondestructive testing. Non-film real time digital radiograph, which has high efficiency and low cost, especially the characteristics of digital image exchangeability and storage convenience, has become the development direction. Because the existing system has the disadvantage of low imaging quality and only being used at low X-ray energy, a high quality imaging system based on scientific CCD camera has been developed, which has high spatial solution and high contrast sensitivity and can be used both at high energy and low energy. This paper introduces the constitution of the system, and designs the relative circuits. The experimental results show that the system has the better imaging quality and wider adapting range for X-ray energy, can needs the requirements of measurement.
