论文摘要
在这封信中，我们报告了离子和电子幽灵成像的演示。相关离子和电子的两光束由光电离过程产生，并加速到相反的方向。使用一个时间和位置敏感的检测器，对于一个梁，即使看到该对象没有空间分辨率的检测器，我们也可以对另一个梁看到的对象进行映像。因此，由于离子与电子之间的相关性，该第二个检测器给出的额外信息可用于重建图像。在我们的示例中，放置在时间敏感探测器前面的金属掩码被用作图像的对象。我们在传输模式下使用此面具展示了离子和电子幽灵成像。这些主要结果是非常有希望的，尤其是在表面科学和纳米物理学中的离子和电子成像中。
In this Letter, we report a demonstration of ion and electron ghost imaging. Two beams of correlated ions and electrons are produced by a photoionization process and accelerated into opposite directions. Using a single time and position sensitive detector for one beam, we can image an object seen by the other beam even when the detector that sees this object has no spatial resolution. The extra information given by this second detector can, therefore, be used to reconstruct the image thanks to the correlation between the ions and the electrons. In our example, a metallic mask placed in front of a time-sensitive detector is used as the object to image. We demonstrated ion and electron ghost imaging using this mask in a transmission mode. These primary results are very promising and open applications especially in ion and electron imaging in surface science and nanophysics.
