Abstract
In an X-ray line sensor, a scintillator layerthat absorbs X-rays in a low-energy range and emits light and a scintillator layerthat absorbs X-rays in a high-energy range and emits light are brought in contact with each other, and further, the thickness of the scintillator layeron the front side is thinner than that of the scintillator layeron the rear side. These make the amount of mismatch small between a light emitting position Pin the scintillator layerand a light emitting position Pin the scintillator layerto X-rays in the low-energy range and X-rays in the high-energy range entered at the same angle from the front side, so that at this time, light emitted by the scintillator layerand light emitted by the scintillator layerare detected by a photo-detecting sectionand a photo-detecting sectionfacing each other. Thus, mismatch between an X-ray transmission image in the low-energy range and an X-ray transmission image in the high-energy range obtained simultaneously can be prevented.
