To address the issues of high detection safety costs, long maintenance times, and poor detection accuracy in the existing manual inspection mode, this article proposes installing detection devices such as industrial cameras and laser scanners on the hoisting container’s roof. During the operation of the lifting system, rigid guide contour laser stripe images are captured, and a laser and machine vision fusion reconstruction model is derived to complete the 3-D reconstruction of the guide point cloud model and obtain guide deformation parameter information. Building upon this, an adaptive center extraction and smoothing algorithm (ACES-R) for the reflective surface stripes of rigid guides is proposed. This method employs an adaptive dynamic contour tracking algorithm and incorporates laser stripe morphology features to effectively segment the laser stripe region. Under complex lighting conditions, including strong reflection interference, overlapping noisy laser segments, and uneven stripe widths, it accurately extracts guide contour information and reconstructs a complete guide point cloud model, outperforming traditional center extraction algorithms. In guide deformation measurement experiments, multiple repeated measurements show that the average error does not exceed 0.2 mm, and the standard deviation (SD) of the measurement results remains within 0.1 mm.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-12"},"PeriodicalIF":5.6,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144550165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, further applications are confined by the inherent NMR low sensitivity and more than an order of magnitude of signal loss. This present study aims at noise reduction of ultrahigh-resolution pure shift NMR spectroscopy and facilitating the direct probing on complex chemical and biological sample systems. A generalized and versatile protocol, which fully exploits the power of multivariate data, is described to enable the reliable noise reduction for 1-D and 2-D pure shift NMR spectroscopy. This protocol enables the fast and reliable recovery and identification of minute signals and very low-concentration metabolites and demonstrates decent application potentials on complex chemical and biological analyses. More meaningfully, as a simple tool and a general concept, this enhancement is well compatible to various pure shift NMR elements and is readily implemented without prior knowledge and complicated setup.

However, due to the lack of deep cross-modal interactions (CMIs) during vision feature extraction, existing methods often suffer from attention bias, which ultimately limits detection accuracy. To address this issue, this article proposes a vision-language cyclic interaction model (VLCIM), which progressively optimizes vision feature extraction by integrating domain prior knowledge and generic large model, effectively bridging the dual-domain barrier between “generic-specific” and “vision-language.” Specifically, progressive cyclic interaction learning is proposed for the first time, which integrates a recursive guidance module (RGM) and CMI strategy to realize bidirectional dynamic fusion and collaborative optimization of vision and language features. Furthermore, the proposed dual-view synergistic detection mechanism (DSDM) enhances discriminative decision responses, significantly improving the model’s boundary perception ability and decision-making accuracy in complex scenarios. VLCIM achieves high-precision defect detection by establishing a cyclic interaction mechanism between domain-specific language features and vision representations. The experimental results on three industrial datasets demonstrate that VLCIM achieves improvements of 5.9%, 5.6%, and 4.1% in mean intersection over union (mIoU) over the state-of-the-art (SOTA) methods, indicating its validity and generalization in different scenarios.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-13"},"PeriodicalIF":5.6,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144614930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The charge measurement under pulsed voltage excitation with optical ellipsometry detection has been realized in previous studies, while they haven’t achieved the charge measurement based on all-optical and noncontact modes. This article designs a novel space charge measurement system under optical excitation and detection methods by introducing high-power pulse laser and ellipsometry techniques. The feasibility of this all-optical method in charge measurement is further verified by experimentally optimizing the excitation and detection modules. First, the pressure wave excitation parameters at the excitation module are evaluated experimentally, which indicates that the signal-to-noise ratio of the system can be improved to 38.02 dB at the laser energy of 340 mJ and the target electrode material of aluminum-sprayed graphene. Then, the main parameters affecting the measurement sensitivity are evaluated based on the established transmission model of the ellipsometry detection system.

To address these challenges, this article proposes a temperature reconstruction deflectometry (TRD) method for noncontact measurement of axisymmetric temperature fields. By employing orthogonal sinusoidal fringe patterns to encode the absolute spatial coordinates on the LCD, the light ray deflection angles can be derived from position shifts and related to refractive index gradients, providing the foundation for accurate temperature reconstruction without relying on Gaussian imaging assumptions. To validate this method, an inverse ray-tracing simulation is conducted to confirm its accuracy through numerical results. Experimental results demonstrate that the TRD method provides higher reconstruction resolution and shows good agreement with K-type thermocouple measurements. While sharing the low-cost and noncontact advantages of traditional background-oriented schlieren (BOS) methods, the proposed approach achieves higher spatial resolution and enhanced displacement detail capture through absolute position encoding. This provides a robust solution for accurate, real-time temperature measurements, making it a promising tool for applications in aerospace, fluid dynamics, industrial diagnostics, and thermal process monitoring.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-9"},"PeriodicalIF":5.6,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144597814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is based on a ring resonator operating in the subgigahertz range, and it exploits the mode-splitting phenomenon to perform differential measurements, wherein one resonance is sensible to the dielectric properties of a sample under test, while the orthogonal resonance serves as an internal reference. This strategy effectively mitigates common-mode perturbations, such as temperature drift. The prototype fabrication was carried out by inkjet-printing a conductive ink into a Rogers RO4003C substrate. The resulting prototype exhibits a nominal resonant frequency near 750 MHz. To characterize the sensor, several samples with known dielectric properties were placed on its surface, and the scattering parameters were measured over the 550-950-MHz frequency range. An analytical fitting procedure was employed to extract the central frequency, amplitude, and quality factor of each resonant peak in the magnitude of the forward transmission coefficient, and these parameters were observed to vary as a function of the samples’ dielectric properties. Additional tests demonstrated the sensor ability to reject common-mode disturbances. The promising results of these investigations are discussed in detail within this article.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-10"},"PeriodicalIF":5.6,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144597990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, weak vital signs are susceptible to interference from vibrations caused by the torque ripple of motor, which leads to the generation of ghost objects and phase noise interference. First, a Doppler combination filtering (DCF) method is proposed to localize the subjects and suppress interference from torque ripple vibrations, utilizing multiple Doppler frequencies associated with breathing for improved precision. Second, an adaptive convergence variational mode extraction-weight pair accumulation (ACVME-WPA) method is proposed to separate breathing and heartbeat signals from the phase signal affected by motor vibration. This method incorporates two key ideas: one involves determining the adjustment rate of the penalty value based on the iterative differences between center frequencies and the other focuses on aggregating multiple phase signals using weighted pairs to enhance performance by considering the HFOV overlap of adjacent virtual radars. Experimental results show that the proposed methods can achieve all-directional measurements of localization, respiration rate (RR), and heartbeat rate (HR) for single subjects with various breathing patterns, with HR mean absolute error (MAE) of 0.026 Hz in the breath-holding experiment, and also work well for multiperson scenarios with different angles and window lengths. In the four subjects’ experiment, the proposed method still works even when subjects are not facing the radar.
