我们证明了原子质心运动干涉产生的物质波自成像。我们发现，不可忽略的原子质心运动和瞬时多普勒频移可以大大改变凝聚动量分布，导致周期性崩溃和复发凝聚衍射概率作为一个函数的固定光场脉冲时间。所观察到的物质波自成像的特征在于，在光场的存在下，原子质心运动引起的布居振幅干涉同时最小化所有高（n>或=1）衍射级并最大化零衍射分量。
We demonstrate matter-wave self-imaging resulting from atomic center-of-mass motion-based interference. We show that non-negligible atomic center-of-mass motion and an instantaneous Doppler shift can drastically change the condensate momentum distribution, resulting in a periodic collapse and the recurrence of condensate diffraction probability as a function of the stationary light-field pulsing time. The observed matter-wave self-imaging is characterized by an atomic center-of-mass motion induced population amplitude interference in the presence of the light field that simultaneously minimizes all high (n>or=1) diffraction orders and maximizes the zeroth diffraction component.
