Influence of radiation source focus in radiography and its correction

REN Da hai 1, YOU Zheng 1, SUN Chang ku 2, YE Sheng hua 2 (1 Department of Precision Instrument and Mechanism, Tsinghua University, Beijing 100084, China) (2 State Key Laboratory of Precision Measuring Technology & Instruments, Tianjin U  
In this paper, the influence of radiation source focus on imaging quality of non destructive testing system is analyzed. The mathematical model for the influence of radiation source focus on real time radiography image is discussed. On the basis of this model, the corresponding algorithm is designed to make correction for it. Meanwhile, the processing result is presented.
