    Abstract:Laser shock peening (LSP) is a surface modification technology that significantly enhance the mechanical properties of materials, commonly improving the fatigue life of critical components such as aero engine blades. However, the high sampling rate of laser-induced plasma spectra and the complexity of physical information challenge spatio-temporal resolution, affecting the stability and consistency of LSP quality monitoring. This study address these challenges by leverageing the ultra-high sampling rate of Narrowband Microchannel Plate Photomultiplier (Nb-MCP-PMT, NMP) GHz to monitor rapid and weak light signals from laser-induced plasma in LSP process. High-speed photography elucidates the physical mechanisms of plasma evolution behind the NMP signal, showing that the 0–1.2 μs period in the NMP signal defines the dynamic balance stage, associated with plasma generation and expansion, while the 1.2 μs–1200 μs period corresponds to plasma diffusion and decay, defined as the attenuation stage of the NMP signal. Key features such as NMP-Min, NMP-Median, NMP-Std, NMP-ADif, NMP-Ske, and NMP-Kur were extracted to capture the periodicity, trend, and non-stationarity of NMP signals. A Transformer-Fusion-Attention mechanism (TRM-F-AM) model was developed to automatically extract temporal depth information and identify key features and frames. Distinct attention weight distributions were observed during the dynamic balance and slow attenuation stages of the NMP signal. The feature set redundancy was minimized, marking critical time periods for LSP process monitoring, specifically frames 1–80 during the dynamic balance stage and frames 155–265 during the slow attenuation stage. The model achieved a prediction accuracy of 99.05 % for LSP surface hardness on TC4 and 7075Al targets, surpassing TCN, LSTM, 1D-CNN, and ensemble learning models. ? 2025

    Abstract:Ultrafast gated image intensifiers are crucial for capturing high-resolution images with sub-nanosecond temporal resolution. This study compares two methods for characterizing optical gating time in these intensifiers: Method I, involving a "laser pulse walkthrough," and Method II, utilizing a fiber optic delay array. Both methods were applied to the same intensifier, with results analyzed for consistency and discrepancies. The findings indicate that both methods yield consistent optical gating times within their standard deviations range, though Method II exhibited greater dispersion at the photocathode edges due to spatial non-uniformity. The study further reveals that while the optical gating time distribution across the photocathode is uniformly consistent, a constant delay exists between different regions. To enhance measurement precision it is recommended to subdivide the photocathode for individual calibration of gating time and delay. These insights are pivotal for improving the precision and reliability of optical gating time measurements in applications requiring sub-nanosecond or even picosecond temporal resolution. ? 2024 Elsevier B.V.

    Abstract:The underdetermined equation in multispectral pyrometer temperature measurement involves simultaneous unknowns of emissivity and temperature, posing a challenging obstacle to achieving accurate temperature inversion. In recent years, constrained optimization algorithms have been increasingly employed to address this issue. However, these algorithms need to set the appropriate initial emissivity values in particular and the imposition of manual constraints on the search range for emissivity. In this paper, a new data processing method that does not require these artificial Settings is proposed. Our method incorporates new objective functions and nonlinear constraints into the inversion of multispectral emissivity and temperature, while employing the Barrier Function Interior Point Method as an optimization tool. In addition, it has to be mentioned that in the blackbody temperature setting of the reference temperature model, the temperature of the blackbody is set very close to the target temperature by the constrained optimization algorithm, which obviously does not meet the needs of large-scale temperature measurement. The data processing method proposed in this paper addresses situations where there is a significant difference between the blackbody set temperature and the target temperature, ensuring both accuracy and speed over a wide range. Experiments demonstrate that our proposed method achieves a relative error of less than 0.42% in emissivity inversion, less than 0.57% in temperature inversion, and a calculation time of under 0.2 s. Our method can be applied to some high-precision and fast temperature measurement occasions that require short processing time and small relative error. ? 2024 Elsevier B.V.

    Abstract:Image dehazing is a representative low-level vision task that estimates latent haze-free images from hazy images. In recent years, Vision Transformers (ViT) have shown promising dehazing performance, leveraging their capacity for global perception through long-sequence dependencies in cost of high resource consumption. Therefore, our approach seeks to integrate the utilization of global information into the Convolutional Neural Network (CNN) framework in a more resource-efficient manner. In this paper, we introduce the Adaptive Center-Surround Receptive Field (ACSRF) network architecture inspired by the central-peripheral receptive field in biological vision for single-image haze removal. This leads to a unique receptive field mechanism that effectively combines both central and surrounding information. Our ACRSF addresses this by initially compressing global information and then merging it within the CNN, significantly boosting the capability to integrate local and global information, and effectively handling dominant color tones. Experimental results on four publicly available real-world image dehazing datasets show that our ACRSF outperforms current state-of-the-art methods in recovering global information, especially in dominant color tones. Importantly, this technology demonstrates its effectiveness in realistic scenarios, contributing significantly to improving traffic safety in adverse weather conditions.

    Abstract:To satisfy the demand of mass spectrometers for high sensitivity and high resolution ion detection, a type of pulse/analog dual-mode, arc-shaped, discrete-dynode electron multiplier (DM-ADD-EM) with 20-stage dynode structure was proposed, and its gain and time characteristics were investigated by three-dimensional numerical simulation. Each of the 2nd-20th dynodes has an arc-shaped substrate consisting of a long arc segment and a short arc segment, attached with a pair of side baffles. The simulation results indicate that the two side baffles play a role in focusing the electron beam to the central regions between them, reducing the number of secondary electrons escaping from the dynode array and, therefore, raising the electron collection efficiency of dynodes. As the radius (R) of arc-shaped substrates increases, the device gain rises. In the case of the 3.6-mm R, there is an optimum long-arc-segment center angle (α = 79°) at which the DM-ADD-EM reaches relatively high analog gain and pulse gain together with preferable time response, and its dynodes in the pulse section can be better protected from electron impact in analog output mode. In addition, the long-arc-segment center angle of the 12th-17th dynodes was further optimized to 84° for suppressing ion feedback. A dynode-configuration-optimized DM-ADD-EM with SiO2-doped MgO-Au secondary electron emission film achieves a pulse gain of 7.2 × 108, an analog gain of 1.3 × 104, a pulse rise time of 3.8 ns, and a pulse width of 9.2 ns under the analog-section/pulse-section voltages of ?1800 V/1000 V, exhibiting significantly improved pulse gain and better time response. These results provide a basis for the design and fabrication of high-performance EMs. ? 2025 Author(s).

    Abstract:A multi-view global calibration method is proposed to overcome the limitations of overlapping regions in multi-view structural vibration measurement. This method establishes a mapping relationship from image points to experimental model points at the outset of vibration measurement, enabling a one-time global calibration of multi-view vibration response data. Furthermore, an image point detection method based on shape-function matching is designed to improve global calibration accuracy. Experimental results demonstrate that the proposed method excels in point detection and global calibration. Finally, the feasibility of this method is validated through vibration experiments on large aircraft fuselage structures. ? 2024

    Abstract:In video snapshot compressive imaging (SCI) systems, video reconstruction methods are used to recover spatial–temporal-correlated video frame signals from a compressed measurement. While unfolding methods have demonstrated promising performance, they encounter two challenges: (1) They lack the ability to estimate degradation patterns and the degree of ill-posedness from video SCI, which hampers guiding and supervising the iterative learning process. (2) The prevailing reliance on 3D-CNNs in these methods limits their capacity to capture long-range dependencies. To address these concerns, this paper introduces the Degradation-Aware Deep Unfolding Network (DADUN). DADUN leverages estimated priors from compressed frames and the physical mask to guide and control each iteration. We also develop a novel Bidirectional Propagation Convolutional Recurrent Neural Network (BiP-CRNN) that simultaneously captures both intra-frame contents and inter-frame dependencies. By plugging BiP-CRNN into DADUN, we establish a novel end-to-end (E2E) and data-dependent deep unfolding method, DADUN with transformer prior (TP), for video sequence reconstruction. Experimental results on various video sequences show the effectiveness of our proposed approach, which is also robust to random masks and has wide generalization bounds. ? 2024 Elsevier B.V.

    Abstract:Sapphire ultrasonic vibration-assisted flexible polishing (UVAFP) is a promising technique for comprehensively improving the surface integrity of machined parts. The technique was performed on an ultra-precision machine tool with the in-situ monitoring systems in this paper, which aims to provide a new perspective for understanding the material removal mechanisms in the sapphire UVAFP process. A Taguchi L9 (43) orthogonal experiment was conducted to investigate the effects of feed distance, spindle speed, ultrasonic vibration (UV), and polishing time on the surface finish and material removal in the process. In addition, the effect of a polyurethane ball tool is not trivial. A single-factor experiment was conducted for exploring it. Based on a laser displacement measurement system and an acoustic emission sensor system, the characteristics of time-dependent ultrasonic amplitude and ultrasonic frequency for the sapphire UVAFP system were analyzed, with the effectiveness of UV demonstrated. Based on a three-component force measurement system, the characteristics of normal force and its relationship with process parameters and tool deformation were analyzed, with macro- and micro-level examined. In conclusion, this paper presents the characterization of UV and polishing force in the sapphire UVAFP process, providing novel insights into understanding the material removal mechanisms of sapphire and even more manufacturing problems. ? 2024 Elsevier B.V.

    Abstract:Discriminative Correlation Filters (DCFs) have recently garnered significant considerable in the field of visual single tracking. However, existing trackers frequently struggle to fully mine the structural complementarity and diversity among various features, resulting in a decline in discriminability in complex scenarios. To address these challenges, we explore a novel context-aware sparse learning (CCSL) framework based on DCFs and hierarchically infer the maximum response represented by each class filter to locate the target confidently. Guided by sparse learning principles, our tracker collaboratively and bidirectionally selects effective spatial elements that encode target appearance through lasso regression and sparse response estimate. Additionally, the target and its surroundings are jointly incorporated into the learning framework, thereby bolstering the discriminability of the learned model. To tackle the optimization problem, we leverage the Alternating Direction Method of Multipliers (ADMM) in the Fourier domain. Furthermore, we introduce a hierarchical inference scheme for target localization that harnesses complementary cues from different features, which leverages historical displacement and multi-modal detection to reveal the tracking state respectively. Extensive experiments are conducted on renowned benchmarks, including OTB-100, UAV123, UAV20L, and TC128, to demonstrate the efficiency and effectiveness of the proposed tracker. These results underscore the tracker's ability to perform robustly in complex scenarios, showcasing its superior discriminative power and accuracy. ? 2024 Elsevier Ltd

    Abstract:Spacecraft component recognition is crucial for tasks such as on-orbit maintenance and space docking, aiming to identify and categorize different parts of a spacecraft. Semantic segmentation, known for its excellence in instance-level recognition, precise boundary delineation, and enhancement of automation capabilities, is well-suited for this task. However, applying existing semantic segmentation methods to spacecraft component recognition still encounters issues with false detections, missed detections, and unclear boundaries of spacecraft components. In order to address these issues, we propose a multiscale adaptively spatial feature fusion network (MASFFN) for spacecraft component recognition. The MASFFN comprises a spatial attention-aware encoder (SAE) and a multiscale adaptively spatial feature fusion-based decoder (Multi-ASFFD). First, the spatial attention-aware feature fusion module within the SAE integrates spatial attention-aware features, mid-level semantic features, and input features to enhance the extraction of component characteristics, thus improving the accuracy in capturing size, shape, and texture information. Second, the multi-scale adaptively spatial feature fusion module within the Multi-ASFFD cascades four adaptively spatial feature fusion blocks to fuse low-level, middle-level, and high-level features at various scales to enrich the semantic information for different spacecraft components. Finally, a compound loss function comprising the cross-entropy and boundary losses is presented to guide the MASFFN better focus on the unclear component edge. The proposed method has been validated on the UESD and URSO datasets, and the experimental results demonstrate the superiority of MASFFN over existing spacecraft component recognition methods. ? 2008-2012 IEEE.
