摘要

利用两个不同焦距的光子筛构建了一个径向剪切干涉仪。利用基于补丁的 UNet 方法提取干涉图的中心骨架，然后应用迭代算法进行波前重建。使用不同的探测器测量了窗玻璃的透射波面，其结果与 ZYGO 干涉仪的测量结果一致。与区域板相比，光子筛通过合理设计小孔的排列，可以抑制高阶衍射，从而提高干涉图的信噪比。此外，通过设计和优化实现自支撑和多功能的光子筛在波前传感和干涉成像中具有重要的应用价值。

Transmitted wavefront testing of window glass with confocal photon-sieves radial-shearing interferometry based on deep learning

Two photon sieves with different focal lengths were used to construct a radial shearing interferometer. A patch-based UNet approach was utilized to extract the central skeleton of interferogram, and then an iterative algorithm was applied for wavefront reconstruction. The transmitted wavefront of a window glass was measured with different detectors, and their results were consistent with the measurement of ZYGO interferometer. Compared to zone plate, photon sieves can suppress higher-order diffraction by reasonably designing the arrangement of small holes, thereby improving the signal-to-noise ratio of the interferogram. Moreover, photon sieves that is self-supporting and multifunctional by use of design and optimization has great application in wavefront sensing and interferometric imaging.

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
