Dual-phase modulation (DPM) is employed as a representative application to demonstrate the principle in mode-division multiplexing (MDM) systems. Although DPM can achieve efficient mode conversion by exploiting interference rather than diffraction, its practical use has been severely constrained by environmental disturbances such as air turbulence, temperature variations, and mechanical vibrations, which induce phase drift and degrade conversion stability. To address this limitation, we introduce a dual-wavelength monitoring and SLM based feedback scheme that enables real-time detection and compensation of phase drift, thereby maintaining stable interference. The performance of the stabilization system is further evaluated under different interferometer arm lengths and control parameters. Experimental results show that the proposed approach effectively suppresses phase fluctuations in short-arm interferometers and ensures stable mode conversion with low modal crosstalk. While mode conversion is used as the experimental example, the proposed scheme is applicable to a broader class of interferometric systems requiring stable complex-field generation and is promising for high-capacity optical communication networks.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"18 2","pages":"1-9"},"PeriodicalIF":2.6,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11411938","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148505141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional dual-mirror synchronous frequency stabilization suffers from periodic variations in the size of adjacent longitudinal mode lock-in regions. Mode hopping, when it occurs, can severely degrade the performance of high-precision gyroscopes. To address this issue, this paper integrates beam transmission matrix theory with vector theory to simulate and analyze the variation of lock-in region thresholds under different frequency stabilization operating points using MATLAB. A novel dual-mirror cooperative frequency stabilization method is proposed. This method employs a preliminary frequency stabilization operating point obtained through mode sweeping. One stabilization mirror induces the sum of clockwise and counterclockwise backscatter angles to approach π, while the other stabilization mirror performs frequency stabilization, thereby achieving minimized control of the lock-in threshold. Experimental results demonstrate that the dual-mirror cooperative frequency stabilization method effectively eliminates periodic variations in lock-in region size between adjacent longitudinal modes. Compared to conventional dual-mirror synchronous stabilization, the lock-in threshold is reduced by approximately 38%, and laser gyroscope accuracy improves by about 53.8%. This approach provides a novel pathway for frequency stabilization control in high-precision laser gyroscopes.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"18 2","pages":"1-13"},"PeriodicalIF":2.6,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11432870","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148505135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intratissue mitochondria can be imaged based on coenzyme fluorescence with a lateral resolution of less than 500 nanometers. Interestingly, a specific single cell deep in the skin can be traced and imaged for hours without motion artifacts using a magnetic interface. Studies with a tunable Ti:sapphire laser for NAD(P)H as well as flavins excitation have been conducted on patients suffering from dermatitis, psoriasis, chronic wounds, and cancer. OMI has also been performed on volunteers during oxygen inhalation as well as on astronauts prior and after long-term space flights. “Energizing” cosmetics with oxygen scavengers was found to change NAD(P)H levels in the skin volunteers. Of particular interest of OMI of human skin is the change of the ratio of free NAD(P)H to bound NAD(P)H as an indicator of altered cellular metabolism that can be determined by autofluorescence lifetime imaging and by using a single excitation wavelength such as 780 nanometers. The fluorescence lifetime of the protein-bound nicotinamide coenzyme is nearly one order larger than the free, non-bound form. Using a biexponential approach, the mean autofluorescence lifetime and the metabolic ratio “short fluorescent component to long fluorescent component” as OMI parameters can be depicted as false-colored stacks of optical sections through the epidermis. In conclusion, two-photon autofluorescence lifetime imaging (“metabolic FLIM”) provides a powerful functional imaging modality for dermatology, pharmacy, and cosmetic research to realize high-resolution optical metabolic imaging of human skin.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"18 2","pages":"1-8"},"PeriodicalIF":2.6,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11409459","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148505299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In practice, experimental frequency response data are often contaminated by outliers originating from laser instability, field-dependent diffraction efficiency variations, and non-ideal peak fitting, which severely bias conventional least-squares estimation due to the strong nonlinearity between alignment errors and image-plane frequency responses. In this work, we demonstrate that coupled alignment errors give rise to a structured single-minimum frequency response surface governed by system geometry, and exploit this physical constraint to develop a model-guided robust calibration framework. A Random sample consensus (RANSAC)-based estimation strategy is employed to identify and exclude outlier measurements without assuming a specific noise distribution, followed by constrained least-squares optimization on the purified dataset. Experimental validation on a collimated mid-wave infrared AOTF imaging system shows that the full-field frequency response modeling error is reduced from 2.4% to below 0.3% after calibration. The proposed method significantly enhances the robustness and accuracy of alignment error compensation, providing a practical solution for high-precision AOTF spectroscopic imaging under real-world measurement uncertainties.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"18 2","pages":"1-8"},"PeriodicalIF":2.6,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11417843","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148509238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
