X-ray chart We provide resolution test charts for X-ray microscopes. Contact us Feature X-ray chart SEM image X-ray microscopy is applied as a high-resolution imaging method in various fields, but charts with sufficiently high resolution are required for evaluation. NTT-AT 's X-ray chart, ...
(μ is permeability of the material), to the Clausius-Mossotti equation demonstrating the connection between the RDP and material properties (this formula is seen in the theory of conductivity as Maxwell Garnett equation, and in the theory of refractivity as the Lorentz-Lorenz equation): ...
The image was normalized with respect to data recorded without the chart. In the projection geometry, the focal spot of the optics acts as a secondary X-ray source, and the half-pitch resolution is limited by the size of the focal spot to approx. 5 μm (i.e., to ~Δx/2)....

The scanning SAXS image in the flow chart of Fig. S1 was elaborated using the multimodal x-ray scattering imaging method11, which allows to analyze the aniso- tropy of the SAXS scattering and, from it, to evaluate the predominant orientation of the crystal, which is perpendicular to the ...

In practice, particles and X-ray ‘stray light’ (from outside the interferometrically imaged field-of-view) can reach the detectors, so that we can adapt the formula for fringe detection from [33]:\(SNR \simeq (VC)^{2}/ \sqrt {(C+B)^{2}+2(C+B)C^{2}V^{2}}\), whereBis...
