论文摘要
干涉法是现代精确测量的主要技术。与光不同，原子与电气，磁性和重力场具有显着相互作用，使它们在干涉应用中的使用尤其是通用。在这里，我们演示了原子干涉仪，以超过$240μm\ times600μm$的面积上图像光学和磁性势景观。我们实验中采用的差异电势会在通过拉姆西脉冲序列可见的原子激光器中产生相位烙印。我们进一步证明了高级脉冲序列如何增强所需的成像特征，例如图像陡峭的潜在梯度。提出了提供半经典分析和匹配数字的理论讨论。
Interferometry is a prime technique for modern precision measurements. Atoms, unlike light, have significant interactions with electric, magnetic, and gravitational fields, making their use in interferometric applications particularly versatile. Here, we demonstrate atom interferometry to image optical and magnetic potential landscapes over an area exceeding $240 μm \times 600 μm$. The differential potentials employed in our experiments generate phase imprints in an atom laser that are made visible through a Ramsey pulse sequence. We further demonstrate how advanced pulse sequences can enhance desired imaging features, e.g. to image steep potential gradients. A theoretical discussion is presented that provides a semiclassical analysis and matching numerics.
