电磁诱导的Talbot效应(EITE)提供了一种非破坏性和无透镜的方式来成像超冷原子或分子(文J·M等人，Appl。太棒了。，98(2011年)081108)。我们研究了一种基于二阶双光子Eite的原子成像方案。采用纠缠光子对作为成像光，实现符合记录。与以往的自成像方案相比，本方案具有非局部成像和图像大小变化可控的特点，有利于EITE在成像技术中的应用。
The electromagnetically induced Talbot effect (EITE) offers a nondestructive and lensless way to image ultracold atoms or molecules (Wen J. M. et al., Appl. Phys. Lett., 98 (2011) 081108). We study an atomic imaging scheme based on the second-order two-photon EITE. Entangled photon pairs are taken as the imaging light to realize coincidence recording. Compared to the previous self-imaging scheme, the present one has the characteristic of imaging nonlocally and of the controllable image variation in size, and thus, it is useful for facilitating the EITE application in imaging techniques.
