The experimental results demonstrate that a QTF force sensor with a balanced structure shows a significant improvement in the Q-factor in an atmospheric environment. With a rational configuration of the QTF probe structure, the Q-factor can be increased by 2-3 times compared to that of the unbalanced ones, even when the length of the attached probe tip (tungsten wire) is longer than 2.5 mm. More precisely, the Q-factor can reach 3000 when the tip length is around 1.0 mm. For a probe length of about 3.5 mm, the Q-factor is ∼1800, which also suits the working of the atomic force microscope (AFM) and shows more stability than the length near 1.0 mm. Nevertheless, the highest Q-factor of the QTF probe does not occur under the most symmetric condition. To explain these results, simplified models associated with the basic QTF probe working situation were simulated using the commercial software COMSOL Multiphysics®. By analyzing these results, we elucidated the mechanism of the QTF probe working in an atmospheric environment and some of its vibration modes connected with its Q-factor. According to the experimental and simulation study results, the balanced QTF probe exhibits a significantly higher Q-factor than conventional ones. The probe tip, with its length near 1.0 mm or 3.5 mm, can achieve an opportune Q-factor for AFM, demonstrating its potential for further improving the performance of QTF probes for atomic force microscopes under ambient conditions.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"97 4","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147717631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we present a prototype NIR ICG imaging system combined with a quantitative framework to simultaneously measure vascular structure and function. The system, incorporating a 785 nm laser, high-sensitivity charge-coupled device camera, and motorized stage, was validated using tissue-mimicking phantoms with vessel diameters of 1 and 2 mm under physiological flow rates. Blood-mimicking fluids circulated via a peristaltic pump simulated realistic hemodynamics. Image processing employed adaptive histogram equalization, bilateral filtering, and Otsu's segmentation within a semi-automated workflow to extract vessel diameter, flow velocity, and perfusion rate with reduced user intervention. The relative errors were below 7% for diameter and flow velocity measurements. By integrating morphological and functional quantification into a unified framework, the proposed approach improves reproducibility over conventional manual ICG analysis. Laser irradiance remained within safe exposure limits.

Despite its advantages over traditional contact transducer-based ultrasound, industrial adoption has been limited by complex optical setups and the inability of multi-mode fibers to deliver a stable Gaussian profile for the pump laser. Here, we report a fully fiber-coupled thermoelastic LU system that uses an anti-resonant hollow-core single-mode fiber to deliver 1mJ nanosecond pulses of 1064nm light, while preserving the fundamental Gaussian mode (pump laser). When combined with a fiber-coupled interferometer (probe laser), a small, flexible, and environmentally robust sensor capable of optically generating and detecting high frequency broadband ultrasound is realized. We demonstrate such an LU system implemented in situ on a four-axis precision lathe. High-resolution thickness gauging is performed, before and after precision cutting, by exciting and measuring a zero-group velocity guided wave mode. The measurements are verified with ex-situ traceable coordinate measuring machine data. Mean absolute deviations of 0.1%, of nominal thickness, before cutting, and 0.2% and 0.3%, after stepped and tapered cuts, respectively, are reported. A theoretical background for thermoelastic ultrasound generation in an elastic waveguide is also presented. Attention is given to the effect of the pump laser profile on wave generation to elucidate the importance of using single-mode laser light. The fiber-coupled system demonstrated is well-suited for use in scientific and engineering sensing applications and facilitates the adoption of LU for industrial non-destructive testing.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"97 4","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147645435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As in any optical system, stray light emerges from, e.g., roughness, as well as particulate and molecular contaminations of the optical elements. It redistributes radiation from well-illuminated to darker regions in the instrument's field of view. We develop and apply a stray light correction based on the deconvolution with respect to a stray light kernel that we were able to reconstruct from inflight measurements. We found that the stray light emergence can be explained best when a spectral component is included in addition to the spatial redistribution of source radiation. Typically, the maximum radiances increase on the order of 5% because of the stray light correction. The stray light corrected cubes enable the derivation of nucleus surface properties from consistently calibrated radiance measurements, as well as the distinction of stray light from dust coma signals or signals from shadowed regions.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"97 4","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147594128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Infrared video bolometers (IRVBs) are an important diagnostic tool for visualizing the spatial distribution of radiated power in such plasmas. However, conventional IRVB signal-processing methods exhibit inherent limitations, as they typically assume a linear temporal variation of dynamically changing background radiation, which restricts the accurate reconstruction of radiated power profiles. To overcome this limitation, this study proposes a novel signal-processing algorithm based on the heat balance equation. The distinct feature of the proposed approach is its ability to physically model time-dependent background radiation, thereby effectively isolating its contribution to the measured signal. The proposed algorithm's performance was validated using phantom datasets with known ground truth. Synthetic tests simulating various discharge scenarios demonstrate that the proposed method reconstructs radiated power profiles with significantly higher accuracy (coefficient of determination, R2≥0.99 in all cases) compared with conventional methods. In addition, the algorithm was applied to representative Korea Superconducting Tokamak Advanced Research high-confinement mode discharges, confirming that the reconstructed total radiated power and its temporal evolution remain physically consistent under realistic plasma conditions. These results indicate that the developed algorithm provides a robust tool for enhancing the reliability of impurity transport and power balance analyses in fusion plasmas.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"97 4","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147628416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its task is to calculate the heat flux distribution on plasma-facing components from the evolution of surface temperature derived from infrared camera measurements. For operational campaign 2 of Wendelstein 7-X, water-cooled high-heat flux divertors made of layers of different materials have been installed into the plasma vessel. The previously employed explicit thermographic inversion code, THEODOR, was deemed insufficient to model these accurately due to the missing capability of defining multiple material layers. This motivated the development of DELVER, which improves upon explicit THEODOR in further aspects by handling 1D, 2D, and 3D modeling with flexible boundary conditions, an implicit solver, arbitrary functional temperature dependency of the orthotropic thermal properties of the materials, and a non-equidistant orthogonal calculation grid. The two codes are being compared using a simple analytical model, the finite element solver ANSYS®, and finally, experimental heat flux calculated from the calorimetry and heat fluxes calculated from infrared measurements. In all test cases, good agreement between DELVER simulations and expected results is achieved.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"97 4","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147633997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
