论文摘要
干扰是可以将波构成最迷人的模式的机制。在感测,成像,捕获或基本研究中,如今的结构波发挥了重要作用,并且正在成为许多有趣的研究的主题。使用连贯的光场作为探针,我们展示了如何将光结构到呈现波前的崩溃和复兴结构中。这些分布是从傅立叶衍射结构的排列的傅立叶光谱中获得的。有趣的是,即使衍射结构不是周期性的,所得的干扰可能会在许多距离尺度上呈现衍射峰的准膜结构。我们在量子机械系统的演变中建立了与复兴现象的类比,并通过数值和实验说明了该计算,与所提出的理论获得了极好的一致性。
Interference is the mechanism through which waves can be structured into the most fascinating patterns. While for sensing, imaging, trapping, or in fundamental investigations, structured waves play nowadays an important role and are becoming subject of many interesting studies. Using a coherent optical field as a probe, we show how to structure light into distributions presenting collapse and revival structures in its wavefront. These distributions are obtained from the Fourier spectrum of an arrangement of aperiodic diffracting structures. Interestingly, the resulting interference may present quasiperiodic structures of diffraction peaks on a number of distance scales, even though the diffracting structure is not periodic. We establish an analogy with revival phenomena in the evolution of quantum mechanical systems and illustrate this computation numerically and experimentally, obtaining excellent agreement with the proposed theory.
