Abstract: A projection-based x-ray imaging system combines projection magnification and optical magnification in order to ease constraints on source spot size, while improving imaging system footprint and efficiency. The system enables tomographic imaging of the sample especially in a proximity mode where the same is held in close proximity to the scintillator. In this case, a sample holder is provided that can rotate the sample. Further, a z-axis motion stage is also provided that is used to control distance between the sample and the scintillator.

Abstract: A scintillated CCD detector system for imaging x rays uses x-rays having a photon energy in the range of 1 to 20 keV. The detector differs from existing systems in that it provides extremely high resolution of better than a micrometer, and high detection quantum efficiency of up to 95%. The design of this detector also allows it to function as an energy filter to remove high-energy x-rays. This detector is useful in a wide range of applications including x-ray imaging, spectroscopy, and diffraction. The scintillator optical system has scintillator material with a lens system for collecting the light that is generated in the scintillator material. A substrate is used for spacing the scintillator material from the lens system.
