In this paper, we proposed and experimentally demonstrated an innovative sensor for dual parametric simultaneous measurement based on Sagnac-interferometer (SI) constructed by double-clad polarization-maintaining fiber (DPMF). The sensor is designed using a 2 × 2 coupler to connect the DPMF, forming an optical fiber loop structure while granted with a Fiber Bragg granting (FBG). The experiment proves that the SI exhibits curvature sensitivity of − 89.1 nm/m−1 from 0.062 to 0.176 m−1 and − 179.09 nm/m−1 from 0.186 to − 0.26 m−1 while temperature sensitivity of − 1.65 nm/°C. By adding FBG to realize dual parametric simultaneous measurement. The FBG has showed sensitivities of curvature and temperature are − 6.97 nm/m−1 and 0.009 nm/°C. The coefficient matrix approach is employed to simultaneously measure both curvature and temperature. The sensor exhibits ultra-high curvature resolution of 1.1 × 10−4 m−1 and achieves dual-parameter simultaneous measurement for curvature and temperature through a simple fabrication process. Its characteristics of high sensitivity and resolution, low production costs, and straightforward manufacturing make its application prospects in industrial manufacturing and aerospace fields broader.</div>","PeriodicalId":474,"journal":{"name":"Applied Physics B","volume":"132 8","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00340-026-08702-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148613413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the key consequences of hyperglycemia is nonenzymatic glycation of biomolecules, including proteins, lipoproteins, and lipids. The aim of this study was to determine the optical properties of adipose tissue in healthy rats and rats with experimentally induced T1DM using multiwavelength refractometry and spectroscopy, followed by data verification through histological analysis and molecular modeling. Glycation of collagen and phosphatidylethanolamine was shown to lead to expansion and destabilization of their hydration shells. A comprehensive analysis revealed a correlation between optical properties, structural changes in tissues, and their hydration. The differences in the optical properties of abdominal fat, arising from pathological glycation and hydration, could enable the development of label-free optical methods to monitor T1DM in experimental settings. This approach may ultimately support new strategies for predicting, diagnosing, and tracking the progression of T1DM in humans.</div>","PeriodicalId":474,"journal":{"name":"Applied Physics B","volume":"132 8","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00340-026-08700-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148366003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This quantity, αeff, is important for quantitative characterization of the impact of temperature variations as well as thermal effects on the optical components. This work demonstrates the use of a spectral domain low coherence interferometer (SDLCI) in common path configuration, along with phase sensitive analysis, to measure effective thermal expansion coefficient of fused silica and sapphire samples with sub-nanometer scale optical path length sensitivity. The phase based optical path length retrieval methodology is first established with simulated data and then validated experimentally. Experiments were performed for phase sensitive optical path difference measurements with sub nanometer scale repeatability in using 840 nm wavelength in the temperature range of 35–70 ºC.

In practical microscopy systems, scanner behaviour is governed by dynamic parameters such as settling time, frequency response and phase delay, that critically influence image quality, particularly at high scanning rates. Here, we present a comparative characterization of two GM systems integrated into custom-built laser scanning microscopy platforms. Rather than evaluating standalone scanner units, both systems were examined as fully assembled components within operational microscopes, allowing combined effects of mirror inertia, driver electronics and feedback control to be assessed. Under identical driving conditions, scanner dynamics were quantified through measurements of step response, amplitude and waveform fidelity and frequency-dependent phase delay. These measurements were complimented by representative imaging examples that directly link scanner dynamics to observable image distortions. The results show that the first GM system exhibits faster step response, smaller phase delay and improved amplitude retention across the operational frequency range of 200–800 Hz, indicating higher dynamic bandwidth. In contrast, the second GM system demonstrates slower response and stronger amplitude attenuation at higher frequencies, leading to reduced usable field of view, geometric distortions and larger phase delay leading to misregistration between forward and backward scans. This study provides practical guidance for selecting and optimizing galvanometric scanners and scan parameters in high-performance laser scanning microscopy.</div>","PeriodicalId":474,"journal":{"name":"Applied Physics B","volume":"132 6","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00340-026-08693-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148173440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
