X-ray的顯微分析主要可分為能量散佈分析儀(Energy Dispersive Spectrometer, EDS)或波長散佈分析儀(Wavelength Dispersive Spectrometer, WDS)兩種。兩者原理上的最大差別在於EDS是量測特徵X-ray的能量,WDS則是量測特徵X-ray的波長。 在定量分析時,則是將X-ray peak能量與其所對應的原素能量相比,並經過原子序(Z)...

ray射线scattering基本原理raysdiffraction Diffraction effects are observed when electromagnetic radiation impinges on peri- odic structures with geometrical variations on the length scale of the wavelength of the radiation. The interatomic distances in crystals and molecules amount to 0.15–0.4 nm which corre...
2.1 Principle of X-ray micro-CT An X-ray is a form of electromagnetic wave, such as radio, infrared, visible, or ultraviolet, which has shorter wavelength than ultraviolet wave, and the energy of each X-ray photon is inversely proportional to the wavelength. Therefore, an X-ray has higher...
X-ray emission is produced by the reflection of a high-energy beam from the surface. Given that each element has its own signature energy, the fingerprint or signature spectrum can be compared to reference spectra. This analysis was used for elements with an atomic number above 10. SEM with...
radiation fields, where photon energy surpasses the ionization potential of valence electrons. The authors demonstrate that both the Keldysh and Reiss parameters are essential to capture the onset of strong-field behavior, revealing deviations from weak-field intensity scaling at higher X-ray intensities...
In recent years, significant progress has been made to improve optic testing and optimization techniques, especially those using X-rays for so-called atwavelength metrology. These in-situ and at-wavelength metrology methods can be used not only to optimize the performance of X-ray optics, but ...
