一个直流热和交流调制的冷慢钾束共同传播，并通过原子德布罗意波干涉仪，由一系列的三个微加工衍射光栅。Talbot-vonLau干涉条纹的形成和感测作为光栅位置的函数与热线测量传输。热光束产生衍射限制的阴影莫尔条纹，而较长的德布罗意布罗意波长的慢光束产生干涉条纹与高可见度的第五和第六空间谐波的阴影莫尔条纹。
A DC hot thermal and an AC-modulated cold slow potassium beam copropagate and pass through an atom de Broglie-wave interferometer, consisting of a sequence of three microfabricated diffraction gratings. Talbot-vonLau interference fringes are formed and sensed by measuring transmission with a hot wire as a function of grating position. The hot beam produces diffraction-limited shadow Moire fringes, while the longer de Broglie wavelength slow beam produces interference fringes with high visibility at the fifth and sixth spatial harmonics of the shadow Moire fringes.
