Scintillator array is composed of a large number of independent crystal columns, which limit the diffusion of visible light in the conversion screen, can improve the X-ray conversion efficiency while ensuring the radiography system to have higher spatial resolution, thus it is an important device in high-energy flash radiography system. There are inconsistency response in the received image due to the different conversion coefficients among the crystal columns of the scintillator array. Only by correcting the inconsistency response can the image be interpreted effectively. In this paper, the correction method of inconsistency response in experimental images is studied. Firstly, the empty field image is obtained by flat plate radiography, then the dark current background and impulse noise are deducted from the experimental image and the empty field image, and finally the pixel division operation is carried out between the experimental image and the empty field image. Aiming at the mismatch between the empty field image and the experimental image in strong vibration environment, a method of shifting the empty field image is proposed to realize the re-matching between the empty field image and the experimental image, and the standard deviation data of the corrected image is used to judge the matching between the two images. Experimental results show that the shifted empty field image can correct the inconsistency response of array screen image in strong vibration environment.
