利用第三代同步辐射光源产生的0.069 nm波长的X射线，获得了光栅作为周期相位物体的分数塔尔博特像。作为散焦距离的函数获得的数据的定量评估提供了关于光束的横向相干性以及关于对象中的相位调制的信息。(C)1997年，美国光学学会。
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.
