A Low-Cost and Big View Field X-Ray Intensifier

A new kind of X-ray image intensifier is presented, which is coupled to million-pixel CCD by lens, is mainly composed of the intensifying screen and the brightness intensifier. It has the advantages of big visual field and low price. It is concluded that the relation between the output brightness that the brightness intensifier detects and the size of the intensifying screen obeys the inverse square law and the resolution of the image intensifier depends on the resolution of its components.
