PI软X射线显微镜应用

软X射线显微镜

软X射线显微镜最常用于研究生物样品的元素组成和结构。 软X射线显微镜的波长范围在300 eV – 3 keV之间，能够实现几百埃（strng）的空间分辨率。

软X射线显微镜的主要优点是能够形成厚的水合生物样品的最高空间分辨率图像，而无需使用电子显微镜技术进行耗时的样品制备。 另外，由于生物样品主要由氢，碳，氧和氮组成，因此它们在水窗中的主要吸收边缘。 因此，软X射线显微镜可提供出色的光谱信息并提供高对比度的图像。

Improving spatial resolution in X-ray microscopy by using tilted angle detector: A simulation study

Conventional x-ray imaging detectors suffer from parallax error when the radiation beam arrives at the detector surface at tilted angle. The image blurring occurs as the radiation penetrates detector material in lateral direction at tilted angle. However, at the photon energies used in x-ray microscopy…
