We experimentally test a recently proposed holographic method for imaging coherent light scatterers which are distributed over a 2-dimensional grid. In our setup the scatterers consist of a back-illuminated, opaque mask with submicron-sized holes. We study how the imaging fidelity depends on various parameters of the set-up. We observe that a few hundred scattered photons per hole already suffice to obtain a fidelity of 96% to correctly determine whether a hole is located at a given grid point. The holographic method demonstrated here has a high potential for applications with ultracold atoms in optical lattices.

低光子数下亚微米光散射体阵列的全息成像

我们通过实验测试了最近提出的全息成像方法，该方法用于对分布在二维网格上的相干光散射体进行成像。在我们的设置中，散射体由带有亚微米大小孔的背照式不透明掩模组成。我们研究成像保真度如何取决于设置的各种参数。我们观察到每个孔几百个散射光子已经足以获得 96% 的保真度，以正确确定孔是否位于给定的网格点。这里展示的全息方法对于光学晶格中的超冷原子应用具有很高的潜力。
