我们考虑了应用于冷原子云最小破坏性成像的在线全息反问题。近共振吸收成像提供了一种简单但破坏性的原子柱密度测量方法。共振成像大大减少了加热，并且可以连续成像。在非共振成像所需的条件下，一般棘手的逆问题可以线性化。原子云柱密度的破坏性最小，定量和高分辨率的图像，然后从一个单一的衍射模式检索。
We consider the inverse problem of in-line holography, applied to minimally destructive imaging of cold atom clouds. Absorption imaging near resonance provides a simple, but destructive measurement of atom column density. Imaging off resonance greatly reduces heating, and sequential images may be taken. Under the conditions required for off-resonant imaging, the generally intractable inverse problem may be linearized. A minimally destructive, quantitative and high-resolution image of the atom cloud column density is then retrieved from a single diffraction pattern.
