“…GoogLeNet has used an inception module that has multiple kernels of different sizes for convolution to ensure more efficient computation [96]. A couple of studies that have been published recently have focused on the fusion of NDT methods through neural networks to inspect various materials, from wooden cultural heritages to common composites [97][98][99][100][101][102]. Here, the text will not give the details of these approaches.…”

Non-destructive testing (NDT) of aerospace structures has gained significant interest, given its non-destructive and economic inspection nature enabling future sustainable aerospace maintenance repair operations (MROs). NDT has been applied to many different domains, and there is a number of such methods having their individual sensor technology characteristics, working principles, pros and cons. Increasingly, NDT approaches have been investigated alongside the use of data fusion with the aim of combining sensing information for improved inspection performance and more informative structural health condition outcomes for the relevant structure. Within this context, image fusion has been a particular focus. This review paper aims to provide a comprehensive survey of the recent progress and development trends in NDT-based image fusion. A particular aspect included in this work is providing critical insights on the reliable inspection of aerospace composites, given the weight-saving potential and superior mechanical properties of composites for use in aerospace structures and support for airworthiness. As the integration of NDT approaches for composite materials is rather limited in the current literature, some examples from non-composite materials are also presented as a means of providing insights into the fusion potential.

“…Additionally, NDT techniques have been widely utilized to ensure the quality and integrity of the production process [3]. Particularly in the field of cultural heritage, of which the subjects under study have an irreplaceable and historic nature, NDT is all the more essential, as to protect the subjects from damages during the restoration and conservation process [4,5]. Recently, a Chinese Bronze Lei was subjected using NDT techniques, enabling the detection of internal defects and ensuring the preservation of historical artifact [6,7].…”

“…Recently, a Chinese Bronze Lei was subjected using NDT techniques, enabling the detection of internal defects and ensuring the preservation of historical artifact [6,7]. Owing to its outstanding resolution and high efficiency, as well as its ability to cover a large area in a short time period, infrared thermography (IRT), as an NDT technique, has hitherto been attracting much research interest in cultural heritage inspection [5,[8][9][10][11][12], in particular, it has been commonly used to evaluate the defects and damages in ancient artworks [13].…”

In recent years, the conservation and protection of ancient cultural heritage have received increasing attention, and non-destructive testing (NDT), which can minimize the damage done to the test subject, plays an integral role therein. For instance, NDT through active infrared thermal imaging can be applied to ancient polyptychs, which can realize accurate detection of damage and defects existing on the surface and interior of the polyptychs. In this study, infrared thermography is used for non-invasive investigation and evaluation of two polyptych samples with different pigments and artificial defects, but both reproduced based on a painting by Pietro Lorenzetti (1280/85–1348) using the typical tempera technique of the century. It is noted that, to avoid as far as possible secondary damages done to the ancient cultural heritages, repeated damage-detection experiments are rarely carried out on the test subjects. To that end, numerical simulation is used to reveal the heat transfer properties and temperature distributions, as to perform procedural verification and reduce the number of experiments that need to be conducted on actual samples. Technique-wise, to improve the observability of the experimental results, a total variation regularized low-rank tensor decomposition algorithm is implemented to reduce the background noise and improve the contrast of the images. Furthermore, the efficacy of image processing is quantified through the structural-similarity evaluation.

“…Along with the rapid development of terahertz sources [2], terahertz detectors [3], and the research of terahertz functional devices [4][5][6][7][8][9], THz technology has developed rapidly in recent years, [10,11], and the ourishing of theoretical knowledge and device design in the three aspects of terahertz wave generation, transmission and detection [12][13][14]. Terahertz metamaterials and metasurfaces have also given terahertz technology a wide range of applications in imaging systems due to the advantages of subwavelength unit scale and exible manipulation of electromagnetic wave amplitude and phase [15]. Due to the unique physical advantages of arti cially fabricated terahertz metasurface in terms of polarization and modulation, which makes it promising for material characterization, security inspection, biomedical imaging, and short-range communication [16][17][18][19][20].…”

In this study, we combined MATLAB with the rigorous electromagnetic field simulation software Computer Simulation Technology to perform a co-simulation method for inverse design of high-efficiency and broadband THz metasurface devices. In the proposed design method, genetic algorithm (GA) is embedded to realize automatic and inverse design. Aiming toward the different requirements of high-efficiency and broadband THz metasurface devices, different objective functions are set to optimize the design of different types of THz metasurface devices. Based on the rigorous electromagnetic simulation and genetic algorithm, the proposed design method can realize automatic and inverse design with high reliability, compared to the theoretical model based on catenary e-field theory. This study provides an important guiding role and an efficient method for designing and optimizing required metasurface devices with practical applied value.
