This paper proposes a color image watermark detection algorithm based on truncated Weibull-Rayleigh (TW-R) distribution and quaternion fast and accurate polar harmonic Fourier moments (QFAPHFMs) magnitude domain. First, we have demonstrated that the magnitude of QFAPHFMs is an ideal watermark carrier. Second, the digital watermark is embedded into the magnitude coefficients of QFAPHFM using multiplication criteria. In order to address the observed heavy tailed phenomenon in the magnitude of QFAPHFMs, we used the MMLE method based on the TW-R model to achieve accurate estimation of model parameters. Finally, a blind watermark detector was developed using the locally most powerful (LMP) decision rule. The experimental results show that even with a large watermark capacity, the proposed algorithm exhibits excellent imperceptibility and robustness, surpassing the existing advanced methods in terms of performance.","PeriodicalId":17382,"journal":{"name":"Journal of The Optical Society of America A-optics Image Science and Vision","volume":"42 7","pages":"885-897"},"PeriodicalIF":1.5,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144821856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

The focal intensity profiles of the composite VOFs and propagation dynamics of the embedded PSs are investigated. Our study reveals that isolated, simple, low-order PSs maintain their topological morphologies while undergoing rotational motion during propagation, whereas high-order PSs or low-order PSs resulting from the superposition of high-order optical vortices (OVs) split into stable, low-order PS-coupled configurations due to the spin-orbit interaction (SOI). For multiple PSs, we discover that interaction between them is significantly influenced by their off-axis positions and initial beam parameters, whereby collision, fusion, annihilation, and revival between them can be realized in a controlled manner. Furthermore, we demonstrate that low-order PS-coupled configurations exhibit remarkable propagation stability and self-recovery properties. These findings offer insights into light-matter interactions mediated by beam engineering and singularity manipulation, with potential applications in microscopic manipulation and information processing systems.","PeriodicalId":17382,"journal":{"name":"Journal of The Optical Society of America A-optics Image Science and Vision","volume":"42 7","pages":"878-884"},"PeriodicalIF":1.5,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144821860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

In the non-astigmatic case, refraction is characterized using axial defocus, field curvature, and oblique astigmatism. For astigmatic eyes, the impact of axial astigmatism is analyzed by exploring its interaction with oblique astigmatism. Theoretical predictions are compared with wavefront simulations performed in Zemax, showing consistent values and spatial distributions. In non-astigmatic eyes, refraction retains rotational symmetry with a radially oriented astigmatism axis. In contrast, astigmatic eyes exhibit symmetry breaking: the spherical equivalent decreases along the axis of axial astigmatism and increases in the orthogonal meridian, while astigmatism presents a binodal pattern. This framework aims to provide a solid theoretical basis that complements both experimental data and optical simulations, offering insight into the mechanisms governing central and peripheral refraction.","PeriodicalId":17382,"journal":{"name":"Journal of The Optical Society of America A-optics Image Science and Vision","volume":"42 7","pages":"1004-1012"},"PeriodicalIF":1.5,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144821863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Modeling the evolution of speckle properties throughout propagation requires solving the beam propagation equation, potentially at the cost of resource-intensive calculations. Here, we derive analytical expressions for the transverse size of speckles by approximating the mean autocorrelation function of the electric field through Wigner function moments. As those moments follow particularly simple propagation laws, this approach allows us to describe the evolution of the mean speckle properties along the beam propagation with the use of a few scalar parameters, hence at a very low computational cost. We highlight the relevance of this approach by plotting the evolution of the speckle size in different examples, including Gaussian-Schell and multiple beam configurations. The formalism we introduce is general and applies to the case of multi-dimensional fields, which is of particular interest for studying the effect, on the speckle characteristics, of space-time couplings in dispersive systems.","PeriodicalId":17382,"journal":{"name":"Journal of The Optical Society of America A-optics Image Science and Vision","volume":"42 6","pages":"842-853"},"PeriodicalIF":1.5,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144821828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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, most of the existing metasurfaces used for encryption mainly concentrate on hologram encryption in the far-field, overlooking the potential functions that can be achieved in the near-field. Under such a circumstance, this work has designed a single-layer dielectric metasurface. It can achieve joint near-field and far-field encryption by means of wavelength and polarization multiplexing. This metasurface consists of specific sub-metasurfaces for holograms and sub-metasurfaces for multi-foci. By combining the periodic arrangement method with the phase coupling method, introducing a T-state matrix to design the phase of the multi-foci metasurface, and using the Gerchberg-Saxton (G-S) algorithm to design holographic phases, it can display four corresponding Morse code dot matrices at 10 µm in the near-field. Also, it can show four holograms in the far-field under four combinations of wavelength and polarization. The designed metasurface improves spatial utilization and information storage capacity. Therefore, it is a promising optical storage medium and has broad applications in optical encryption as well as wavelength and polarization multiplexing.","PeriodicalId":17382,"journal":{"name":"Journal of The Optical Society of America A-optics Image Science and Vision","volume":"42 6","pages":"788-794"},"PeriodicalIF":1.5,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144821843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}
