Abstract

Fractional Talbot images of optical gratings acting as periodic phase objects have been obtained by use of x rays of 0.069-nm wavelength from a third-generation synchrotron radiation source. Quantitative evaluation of the data obtained as a function of defocusing distance provides information on the lateral coherence of the beam as well as on the phase modulation in the object.

摘要

利用来自第三代同步辐射源的波长为0.069纳米的X射线，获得了作为周期性相位物体的光栅的分数塔尔博特图像。对作为离焦距离函数获得的数据进行定量评估，可提供有关光束横向相干性以及物体中相位调制的信息。
