Within the tensor polarization holography theory framework, coefficients A and B, representing the scalar and tensor components of photoinduced changes in the dielectric tensor, respectively, play a pivotal role in manipulating the reconstruction wave. Accurate measurement and control of A/B are essential for achieving specific functionalities. In this Letter, we present a straightforward and effective method for measuring coefficients A and B, enabling independent observation of their variations while determining A/B. Unlike previous methods, this approach eliminates the influence of the interference angle, simplifies the experimental process, and accommodates the arbitrary polarization state of the recorded hologram. It provides a powerful means of precisely controlling A/B through exposure adjustment, facilitating the fabrication of advanced optical devices for diverse applications.","PeriodicalId":19540,"journal":{"name":"Optics letters","volume":"50 7","pages":"2153-2156"},"PeriodicalIF":3.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143753923","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}

However, previous methods for generating conjugate topological vortex beams in the rotational speed detection process rely on a series of bulky optical elements, such as the spatial light modulator (SLM) or digital micromirror device (DMD), making the system complex and difficult to integrate. In this Letter, we propose a method to generate conjugate topological vortex beams via a single-layer metasurface, thereby realizing, to the best of our knowledge, the first compact version of an RDE-based rotational speed detection system. By analyzing the adjacent frequency peak gaps in echo light signals, the rotational speed of a rotating target can be accurately measured, with the maximum average relative measurement error being 0.812%. This method paves the way for the development of miniature and compact RDE-based metrology devices, which are particularly suitable for applications with limited volume and payload, thereby enhancing the practical implementation of RDE-based metrology.","PeriodicalId":19540,"journal":{"name":"Optics letters","volume":"50 7","pages":"2259-2262"},"PeriodicalIF":3.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143754053","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}

However, existing CSI systems lack compact, effective encoding designs coupled with fast, high-quality decoding methods. This paper presents a CSI system with a compact reflective optical path design based on a digital micromirror device (DMD), which facilitates additional independent compressive measurements by switching DMD patterns, thereby improving reconstruction accuracy. The system also establishes a direct one-to-one mapping between object points and image points, simplifying the design of the patch-based reconstruction algorithm. Leveraging this feature, a transformer-based reconstruction method is proposed, which divides measurements into patches and employs a transformer network to capture long-range dependencies and inter-patch similarities, reconstructing coefficients under a spatial-spectral dictionary for each patch. The proposed system and method achieve efficient acquisition and reconstruction of 256 × 256 × 22 spectral image data cubes across the 465-675 nm wavelength range.","PeriodicalId":19540,"journal":{"name":"Optics letters","volume":"50 7","pages":"2362-2365"},"PeriodicalIF":3.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143753587","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}
