Abstract
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.
