However, conventional OVA design typically constrains the shapes of the constituent sub-vortices to parametric equations, which limits the exploitation of shape-related degrees of freedom within OVAs and hinders their adaptability to emerging materials with novel circularly symmetric crystalline structures. In this work, we propose a discrete beam shaping method that integrates discrete path integration with the Fourier shift theorem, enabling flexible customization of both closed and open geometric patterns, including both parametric and non-parametric shapes. Experimentally, we demonstrate polygonal OVAs composed of tailored sub-vortices (e.g., triangle, square, hexagon), achieving full spatial utilization in close-packed OVAs and genuine self-similarity between fractal OVAs and their sub-vortices. Furthermore, we introduce a polar lattice coordinate system to generate radially distributed OVAs featuring open linear segments. This advancement provides a strategy for precise control over multiple degrees of freedom in OVAs, thus paving the way for expanded applications in structured light fields.</p>","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 18","pages":"37489-37498"},"PeriodicalIF":3.3,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145125637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
