摘要

We extend thework of photon sieves to spiral photon sieves (SPSs) for the generation of a hard-x-ray vortex.A robustndigital prolate spheroidal window, which has an optimal energy concentration at low frequencies, was used to ad-njust the number of pinholes on each ring of the SPS. It was demonstrated that an SPS has better spatial resolution andnlower background than a spiral zone plate using the specified smallest structures condition. The intensity at thencenter of the dark core is difficult to damp to true zero, primarily owing to current limitations of high-aspect-rationmetal nanostructures. The diameter of the dark core increases as the charge value increases. However, the FWHMofnthe doughnut-shaped ring and background will also increase. Our results pave the way toward the design of high-nperformance SPSs for the generation of a hard-x-ray vortex. © 2010 Optical Society of America
