用聚毛细光学元件聚焦和准直Ｘ射线Ｘ射线光学元件的发展始终是挑战性的。在Ｘ射线波长，多数材料的折射率接近１，而由菲汉耳方程决定的反射系数也小，除非使用掠入射结构。因此，不论是普通折射光学元件还是反射光学元件都不适合多数应用。甚至专为Ｘ射线应用发展的掠入...

Focusing and collimating with poly-capillary optical elements The development of X-ray X-ray optics has always been challenging. At X-ray wavelengths, the refractive index of most materials is close to 1, and the reflection coefficient, as determined by the Philippine Horn equation, is small unless a grazing incidence structure is used. Therefore neither the ordinary refractive element nor the reflective optical element is suitable for most applications. Even for X-ray application development of grazing ...
