首次报道了基于氟化锂（LiF）成像辐射探测器和X射线管结合多毛细管光学系统的台式实验室系统的高分辨率X射线成像的新结果。在本文中，参考对象的成像实验，以及厚的地质样品，显示了一些这种方法的潜力，一个紧凑的实验室X射线显微镜设备的发展。多功能LiF成像探测器的高空间分辨率和动态范围基于对LiF晶体和薄膜中X射线诱导色心的光致发光的光学阅读，使我们能够使用非常简单的接触成像技术。在生物医学成像诊断、X射线源和光学元件的表征、材料科学和光子学等领域可以预见有前途的应用。
Novel results on high-resolution X-ray imaging by a table-top laboratory system based on lithium fluoride (LiF) imaging radiation detectors and a X-ray tube combined with polycapillary optics are reported for the first time. In this paper, imaging experiments of reference objects, as well as thick geological samples, show some of the potentialities of this approach for the development of a compact laboratory X-ray microscopy apparatus. The high spatial resolution and dynamic range of versatile LiF imaging detectors, based on optical reading of photoluminescence from X-ray–induced color centers in LiF crystals and films, allow us to use very simple contact imaging techniques. Promising applications can be foreseen in the fields of bio-medical imaging diagnostics, characterization of X-ray sources and optical elements, material science and photonics.
