摘要： An imaging technology for fuel cells is based on x-ray microscopy. A metrology system images the electrochemical interaction areas of solid-oxide fuel cells (SOFC) in-situ. This system takes advantage of both the penetrating power and elemental absorption contrast of hard x-ray radiation to image the internal interaction areas in a SOFC. The technology can further take advantage of the strong dependence of the x-ray absorption on material type and energy to distinguish the four major material types: cathode, electrolyte, air, and low-Z contaminants such as sulfur.

摘要： Methods for fabricating refractive element(s) and aligning the elements in a compound optic, typically to a zone plate element. The techniques are used for fabricating micro refractive, such as Fresnel, optics and compound optics including two or more optical elements for short wavelength radiation. One application is the fabrication of the Achromatic Fresnel Optic (AFO). Techniques for fabricating the refractive element generally include: 1) ultra-high precision mechanical machining, e.g,. diamond turning; 2) lithographic techniques including gray-scale lithography and multi-step lithographic processes; 3) high-energy beam machining, such as electron-beam, focused ion beam, laser, and plasma-beam machining; and 4) photo-induced chemical etching techniques. Also addressed are methods of aligning the two optical elements during fabrication and methods of maintaining the alignment during subsequent operation.

摘要： 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.

摘要： A lithography apparatus having achromatic Fresnel objective (AFO) that combines a Fresnel zone plate and a refractive Fresnel lens. The zone plate provides high resolution for imaging and focusing, while the refractive lens takes advantage of the refraction index change properties of appropriate elements near absorption edges to recombine the electromagnetic radiation of different energies dispersed by the zone plate. This compound lens effectively solves the high chromatic aberration problem of zone plates. The lithography apparatus allows the use of short wavelength radiation in the 1-15 nm spectral range to print high resolution features as small as 20 nm.

摘要： A digital x-ray phase contrast soft tissue imaging and mammography system offers significant cancer detection sensitivity and a significant improvement in accurate detection and interpretation of mammograms. In addition, the proposed system produces digital mammograms and thus has the advantages of digital mammography. The system overcomes the limitation of the current approaches to mammography using phase contrast effects and offers substantially higher performance than the current mammography used in hospitals and clinics. The proposed system uses the phase contrast imaging, in a breast and other soft tissue structures, instead of absorption contrast employed in the current x-ray mammography, allowing detection of smaller disease structures with substantial reduction in radiation dose.

摘要： 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.
