However, its multi-shot nature makes it highly susceptible to motion-induced phase errors, leading to severe reconstruction artifacts in dynamic scenes. Here, a robust motion-resistant phase-shifting profilometry method based on principal component analysis (mrPCA-PSP) is proposed. By leveraging PCA to separate signal from noise, non-uniform phase shifts induced by motion in each raw fringe image are compensated. Through image rectification and unknown phase shift estimation, the method achieves high-precision phase retrieval for objects moving in arbitrary directions using only three phase-shifted fringe images. Experimental results in complex dynamic scenes demonstrate that mrPCA-PSP exhibits significantly enhanced motion robustness compared to traditional PSP. By implementing it in a GPU-accelerated multi-view structured light fringe projection system, motion-induced errors are effectively suppressed, achieving real-time, motion-artifact-free, high-precision 3D measurements at speeds of up to 100 Hz. These capabilities position mrPCA-PSP as a promising solution for high-speed, real-time 3D shape measurement in dynamic environments, with applications in industrial inspection, robotic navigation, and human-computer interaction.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"230 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143836971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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, unmanageable crystal nucleation presents long-term challenges to artificial regulation of the growth of HPSCs. Here a generalized growth strategy of HPSCs by light-thermally synergistic modulation nucleation is reported. The light-excited carriers of perovskite pre-nucleation clusters form strong electrostatic layers, leading to stronger repulsion between the clusters and finally inhibiting nucleation driven by thermal energy. The crystal nuclei concentration in the precursor is greatly decreased by as much as 2 orders of magnitudes, which enables the growth of an individual single crystal in one synthesis with a 96.8% high yield. The synthesized and processed perovskites exhibited good stability underwater or long-term light irradiation. The crystals can be both size-, type- and shape-controlled by manipulating the different crystallization parameters. This light modulated nucleation route would help optimize the solution-based HPSCs growth and promote their applications.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"108 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143832385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 ability of LiDAR to resolve objects is constrained by the Abbe-Rayleigh diffraction limit due to the wave nature of light. Superoscillation, as a far-field super-resolution technique, theoretically allows for the generation of arbitrarily small light spots. However, its practical implementation is primarily validated within the microscopic domain because of the weak super-diffractive information and strong sidelobe noise. Consequently, its application in far-field super-diffractive imaging with light waves remains insufficiently explored. In this study, the first functional prototype is presented for super-resolution imaging using super-oscillatory illumination in LiDAR. By utilizing a specifically engineered super-oscillatory light field with confocal illumination, super-resolution imaging of a target at a distance of 20 meters is achieved.

However, in-plane manipulation of optical beams remains challenging, especially in the presence of complex scattering phenomena such as branched flow. Here, the controlled design of branched light flow, beginning with fundamental beam refractions in soft nematic liquid crystals (NLCs), is demonstrated. Leveraging a multistep photoalignment technique, disordered optical potentials are generated by exploiting the intricate inhomogeneity of NLC domain mesostructures. By tuning the density of these domains, the correlation length of disordered potential can be adjusted, thereby enabling control over the branched flow of light. The unconventional intensity statistics and the rapid fidelity decay along propagation are revealed through in-plane light scattering, illuminating the complex dynamics of light–matter interactions. Furthermore, a phenomenon that transcends the classical understanding of branched flow is uncovered: the emergence of unilateral branches at the boundary of disordered regions of NLCs. This work underscores the unique capabilities of the customizable soft matter platform in shaping the very nature of light transport in planar disordered media and offers a new approach toward novel soft photonics and diffractive optical computing.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"16 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143832386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

For decades, it has been widely understood that this spin-induced OT only occurs on anisotropic (e.g., dumbbell and rod) particles or absorbing (e.g., gold) spheres. In contrast to previous interpretations, herein a nontrivial mechanism is presented for generating and measuring spin-determined OTs on non-absorbing spheres. This counterintuitive OT emerges from the gradient of the spin angular momentum, which imposes non-uniformly distributed force/energy vectors on the particle. The opposite force vectors on both sides of the beam induce extraordinary spin-gradient OTs whose sign depends on the particle's permittivity rather than its position. This negative spin-gradient OT is more readily observable on dielectric particles due to the elimination of the predominant positive absorbing OT. Experimentally, the spin-gradient OT is exquisitely measured using the polystyrene sphere delicately labeled with a tiny tail, showcasing its strong correlation with light polarization. The study enriches the fundamental understanding of OT, offering marvelous applications that circumvent heating effects in physical and biomedical sciences.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"7 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143832383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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, resolution degradation caused by the system's imperfect point spread function (PSF) necessitates advanced deconvolution algorithms. Despite progress, a comprehensive review of these techniques in the OCT field is lacking. This review examines the current state of deconvolution strategies to overcome the PSF-induced blurring and discusses their applications, challenges, potential solutions, and future directions. By surveying previous works, this work identifies technical milestones and categorizes them accordingly. Deconvolution in OCT continues to evolve, contributing to both fundamental research and biological imaging. Despite significant improvements in image resolution and signal-to-noise ratio (SNR), challenges remain in real-time clinical imaging, including optimization robustness and balancing accuracy with computational complexity. Future developments need to address these challenges, emphasizing the importance of comprehensive methodologies that integrate deconvolution with other image enhancement solutions like noise removal. Interdisciplinary collaboration and validation are crucial. The future of OCT deconvolution is rich with opportunities, from combining real-time artificial intelligence (AI)-aided OCT and multi-modal imaging to exploring complex algorithms with growing computational capabilities. As clinical adoption nears, rigorous testing and ethical diligence remain essential to fully realize the potential of OCT deconvolution techniques.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"183 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143832388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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, current storage technologies are primarily based on single-channel and visible light regions, limiting the security of existing optical information storage. Thus, it is necessary to develop new materials and a multi-channel encryption strategy based on invisible light. In this work, we report a Ruddlesden-Popper phase Ba<sub>2</sub>SnO<sub>4</sub> phosphor with photostimulated luminescence (PSL) properties, and enhance its near-infrared emission through fluorine substitution to achieve multi-level optical information encryption. The enhanced mechanisms are elucidated by investigating the effects of fluorine-induced lattice distortion and the enrichment of self-trapped excitons (STEs) due to increased oxygen vacancies. Additionally, density functional theory calculations reveal the influence of F substitution on the formation energy of oxygen vacancies, providing insight into the specific oxygen vacancy sites that contribute to the enrichment of STEs. Furthermore, it is observed that the PSL properties exhibit repeatable capabilities. Based on this, a dual-channel encryption scheme using visible and invisible light for information encoding is designed, offering a new approach to optical information storage and encryption.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"29 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143836925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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, attempts to improve SERS performance by fabricating metal nanostructures with sharper hotspot structures have encountered bottleneck, as the extremely short SERS effective distance remains unresolved. Here, a strategy to modulate SERS hotspots by additional long‐range local field effect is proposed. Stable opal photonic crystal (OPC) is developed for Au deposition, which modulates the incident light field directly, rather than merely optimizing the metal nanostructure, thereby significantly enhancing the hotspots generation. OPC substrate introduces structural discreteness to the deposited Au layer, also effectively improving hotspots intensity. Au layer prepared by direct evaporation can detect signal molecules with adsorption concentration of 10−9 m. The SERS properties of identical Au nanostructures are further enhanced 66.8 times by OPC effect. The coupling between OPC effect and localized surface plasmon resonance (LSPR) effect induces strong elastic scattering of incident photons over a large range, substantially enhancing Raman scattering 300 nm away from the substrate surface, facilitating the detection of larger‐sized objects. Dual‐local field effect modulating both the LSPR effect and incident photons, significantly enhances the SERS performance of identical metal nanostructures, offering broader effective range compared to conventional strategies, providing an effective approach for practical application.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"183 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143824904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
