论文摘要
我们概述并在实验上演示了一种使用带有单像素探测器的传统量子幽灵成像对纯相对象进行映像的方法。我们提供了该过程的理论描述，显示了如何将相位信息嵌入到空间纠缠的光子对的相关测量中，其中只有一个对与对象相互作用。使用成对的数字投影掩码，一个仅幅度，仅一个相位，我们重建对象的两个部分相位图像。使用这两个图像，我们可以在没有歧义的情况下检索对象的完整详细相位剖面，我们在显示相位步长和梯度的对象上进行了证明。
We outline and experimentally demonstrate a method to image pure phase objects using traditional quantum ghost imaging with single pixel detectors. We provide a theoretical description of the process, showing how phase information is embedded in the correlation measurements of spatially entangled photon pairs in which only one of the pair interacts with the object. Using pairs of digital projective masks, one amplitude-only and one phase-only, we reconstruct two partial phase images of the object. Using both these images, we can retrieve the full detailed phase profile of the object without ambiguity, which we demonstrate on objects exhibiting phase steps and gradients.
