The study of resolution of X-ray digital imaging system based on the double proximity focusing X-ray image intensifier

To the X-ray imaging system, resolution is one of the significant parameters to measure the imaging quality. In order to develop a high-resolution X-ray digital imaging system used for electronic industry, our laboratory has worked out the systemic resolution mathematical model of the X-ray imaging system. In this model, several factors are considered, such as the size of focus of the X-ray source, the double proximity focusing X-ray image intensifier and the influence of CMOS camera. Tests show the model accords with the truth. So it would have some value to the design of the similar systems.
