Previous polarization imaging methods mainly focused on the degree of polarization (DOP) of the backscattered light, and assumed it as a constant, resulting in no physical meaning of the optimization calculation. In this paper, particular attention is paid to the DOP of the target light, and the DOP of the backscattered light is evaluated as a function of the DOP of the target light. The global distribution of the backscattered light and its polarization degree is obtained using low-pass filtering in frequency domain. And, a novel constraint model is proposed to further confine the value range of the DOP of target light. In the proposed method, the DOP of the target light and the cutoff frequency of the low-pass filtering are chosen as the inverse parameters. To obtain the above two parameters, a two-layer multi-indicator framework is built. The proposed method can automatically realize underwater image recovery, and no background area or any prior information is required. The laboratory simulation experimental results show that the contrast and clarity of the reconstructed images have been significantly improved with different polarization characteristics under various turbidities.</div></div>","PeriodicalId":19586,"journal":{"name":"Optics Communications","volume":"584 ","pages":"Article 131848"},"PeriodicalIF":2.2,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143808438","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}

Bistability operated in the system was theoretically predicted in both mathematics and physics, and was numerically simulated to demonstrate by a typical bistable curve diagram. We investigated the stability of the equilibrium point, and bifurcation or limit cycles of the system as a function of the coupling strength and the delayed time. Our theory revealed that the switching function identified as the anti-phase mechanism guided the system from regular to complex behavior, and was numerically simulated to demonstrate by a typical switching wave diagram. We also displayed a quasi-periodic route to chaos and hyperchaos by adding the coupling strength, where hyperchaos was diagnosed by its corresponding two positive Lyapunov exponents. We carried out an analysis of the periodic oscillation frequency and bifurcation while the critical coupling strength is found. Our analysis of the Hopf bifurcation controlled by the delayed time, it was found how the different critical delayed time led to bifurcation processes. A display of dynamic behavior was carried out while the system exhibited some typical nonlinear dynamic behaviors, such as chaos, hyperchaos and quasi-period as well as coexistent scenarios. We also given a route to chaos through a quasi-period and a route to a quasi-period away from chaos. The hyperchaotic four-scroll strange attractor was illustrated to be characterized by ergodicity, complexity and randomness. The result has a reference value for an optical bistable device, a hyperchaotic emitter, laser technology, and their applications.</div></div>","PeriodicalId":19586,"journal":{"name":"Optics Communications","volume":"585 ","pages":"Article 131850"},"PeriodicalIF":2.2,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143828140","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 sensor probes the sensitive phase response at plasmonic resonance using stable spectral color profile. In the optical design, the plasmonic sensor surface is placed inside a polarizer pair with perpendicular polarization orientation. The polarizer pair originally does not allow excitation light to pass through. At plasmonic resonance, the differential phase response between p- and s-polarization light rotates the polarization ellipse, which allows the excitation light to leave the polarizer cavity. Furthermore, the differential phase response is wavelength dependent and a phase-spectral color profile is created at the SPR image. The spectral-phase color profile is not sensitive to environmental vibration comparing to conventional interferometric phase SPR detections.

We also provide a distance formula that determines the position at which the FFFPLGB begins to acquire its perfect property. This distance formula can improve the practical implementation and operation of the FFPLGB. Quantitative research findings show that the FFPLGB, owing to its unique multi-ring structure, possesses more superior perfect property compared to classical perfect vortex beam. Compared to the declining received probability of Laguerre-Gaussian beam (LGB) with increasing OAM mode, FFPLGB demonstrates the ability to maintain similar OAM spectrum distributions across different OAM modes. Furthermore, the OAM spectrum distribution of FFPLGB remains largely invariant to changes in radial orders, highlighting its robustness and superior performance in optical applications.
