e.g. a CCD or CMOS camera coupled with ascintillatorand an optical objective lens, which records X-ray intensity after the sample. There is no other X-rayopticsafter the sample. X-rays transmit through the sample then directly project
As a result, X-ray micro- and nanofocussing can be implemented today by either diffractive (example: Fresnel zone plates), reflective (examples: Kirckpatrick-Baez mirror, waveguides) and refractive optical elements (example: compound refractive lenses), and/or combinations thereof. X-ray optics ...
X-Ray focusing technologies utilized for HXRM instruments can broadly be grouped into three categories based on whether they employ diffractive, reflective, or refractive optics (Snigirev and Snigireva, 2008). Again, it is not our intent in this chapter to discuss the details of these technologie...
Here we present the concepts of these optical systems applied to high-energy astronomy, the basic reconstruction methods including some useful formulae, and the trend of the expected and observed performances as function of the system designs. We review the historical developments and recall the ...
X-ray techniques for the non-invasive investigation of the inner structure and elemental composition of matter at the micro- and nanoscale require high-performance X-ray optics. For this purpose, various types of reflective, refractive, and diffractive optical elements have been developed in the las...
Forum: Optics Optical Measurements of the Sun's radiance and ray tracing Summary: This is a hobbyist project I am working on. I am building an instrument to measure radiance from the sun at 500 nm, using optically filtered photodetector with bandwidth ± 10 nm. This type of science can ...
1. An x-ray fluorescence system comprising: an x-ray illumination system comprising an x-ray source and an x-ray optical train; a mount to hold an object to be examined; a means for moving the mount; and an x-ray detector; in which the x-ray source additionally comprises: a vacuum ...
46. The x-ray source of claim 40, additionally comprising an x-ray optical element; said optical element positioned such that x-rays emitted by a sub-source enter said optical element and are directed onto a predetermined position within the vacuum chamber. 47. The x-ray source of claim 27...
