However, the non-linear and non-uniform deflection of light introduced by the prism components, result in geometric distortion, dispersion, and ghosting artifacts. To address these challenges, a robust reconstruction framework is developed based on multi-channel structure-guided fusion. The framework first identifies ghosting regions through theoretical and experimental analysis of ghosting artifacts, enabling precise separation of degraded and smooth areas. Then, distortion and dispersion are corrected while high-quality structural information is transferred across channels, effectively suppressing ghosting and enhancing overall image quality. Besides, an objective evaluation metric termed ghosting-dispersion index (GDI) are proposed to quantitatively measure the severity of ghosting and dispersion. A multi-channel RPIS is fabricated, and experimental results demonstrate that the proposed method consistently achieves the highest GDI scores even when the field of view (FOV) is expanded by 1.15 times, and displays superior correction and reconstruction performance as well as its robustness and adaptability to diverse environments, significantly outperforming existing algorithms for both indoor and outdoor scenarios.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"34 15","pages":"26960-26980"},"PeriodicalIF":3.4,"publicationDate":"2026-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148760636","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}

To resolve the difficulty of directly obtaining a point spread hologram of an ideal-sized point object with high resolution and high signal-to-noise ratio (SNR) through the Interferenceless coded aperture correlation holography system, we propose a method in this paper for directly calculating and obtaining a resolution-enhanced point spread hologram (RE-PSH) by large-sized point objects. In the proposed method, the RE-PSH is obtained via the modified deblurring by pixel reassignment algorithm, and a high-resolution point spread hologram library is further derived through a two-step iterative deconvolution method for 3D imaging. Simulations and experiments have demonstrated that the system maintains high resolution and high SNR in both 2D and 3D imaging even at light intensities 100 times higher than the ideal flux. The proposed method does not require recording information of an ideal-sized point object, which will significantly reduce the hardware requirements and computational complexity of the system, thereby providing a technical foundation for its application in weak-light imaging.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"34 15","pages":"27964-27976"},"PeriodicalIF":3.4,"publicationDate":"2026-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148761634","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}

Although deep learning has achieved significant progress in this field, the reconstruction effect is largely affected by the high quality real-world data, which restricts its use in resource-limited situations. In this paper, we present a pre-processed speckle-correlation learning technique that effectively decreases the differences in data distribution under various scattering conditions. This enables the network to acquire more reliable physical prior knowledge, thus greatly enhancing the model's generalization ability. The experimental results show that, compared with the conventional speckle correlation learning method, the proposed approach obtains a better structural similarity index and peak signal-to-noise ratio on the test data and exhibits superior stability against unknown scattering media with different statistical distributions. Particularly, our method can recover real-world data by using only simulated data for training, completely freeing us from the dependence on real-world data. This offers a robust and feasible solution for scattering imaging in a scarce-resources environment.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"34 15","pages":"27038-27052"},"PeriodicalIF":3.4,"publicationDate":"2026-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148765343","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}

Here, we theoretically demonstrate that these seemingly incompatible paradigms can be unified through a topological Anderson random laser (TARL), where disorder itself induces a topological phase that enables robust lasing. Starting from a trivial photonic lattice, we show that engineered disorder drives the system into a topological Anderson insulator regime, generating emergent chiral edge states that serve as boundary-selective lasing channels. Remarkably, the TARL exhibits rapid mode selection toward a single edge state, producing an ultranarrow emission spectrum and enhanced slope efficiency optimized near disorder strength with maximal topological mobility gap. Furthermore, they exhibit single-mode-like coherence properties, deviating from Kardar-Parisi-Zhang behavior in conventional chiral topological lasers, while remaining significantly more robust against local perturbations than conventional random lasers. Our findings establish a disorder-enabled flexible route to topologically protected single-mode lasing and introduce a fundamentally new design principle for robust, high-coherence photonic light sources.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"34 15","pages":"27932-27947"},"PeriodicalIF":3.4,"publicationDate":"2026-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148759517","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 methods often struggle to preserve intricate anatomical structures while maintaining computational efficiency, which hinders their application in high-quality clinical scenarios. Here, a high-quality medical content rendering framework based on anti-aliased 3D Gaussian splatting is proposed for interactive light-field displays. A display-aware anti-aliasing strategy is introduced to regulate the projected 2D covariance matrices during Gaussian projection, significantly enhancing the rendering quality of high-frequency anatomical details. To facilitate downstream light-field encoding, the optimized 3D Gaussians are further transformed into smooth textured meshes. Furthermore, direct light-field image synthesis is realized through mask-addressing-based coding, bypassing the need for redundant dense-view rendering. Real-time hand-gesture interaction is seamlessly integrated using a Leap Motion controller. Experimental results demonstrate a 1.37 dB average PSNR improvement over the original 3D Gaussian splatting baseline. Notably, the proposed framework achieves real-time interactive rendering at over 109 FPS on a custom-developed 8 K light-field display prototype while delivering superior reconstruction fidelity and visual quality compared with representative NeRF-based and explicit baselines.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"34 15","pages":"27213-27231"},"PeriodicalIF":3.4,"publicationDate":"2026-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148759938","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}
