Special Issue Information
Dear Colleagues,
Advanced NDT (nondestructive testing) techniques are excellent tools in order to safely maintain structures such as bridges, tunnels, and buildings, as well as cars, airplanes, ships, etc. Over the course of several decades, NDT techniques were developed to be more precise and automatic than conventional techniques, which are based on human experience. Laser ultrasonics is one such technique, which has fast defect imaging performance for plate-like materials. Machine vision is also developing well to detect some flaws in structures and materials. This vision technique is now converged with artificial intelligence and big data to clarify some targets from objects quickly and automatically. Advanced NDT techniques can involve many methods, such as holography, shearography, speckle photography, ESPI, etc. These techniques are now being developed for application in the evaluation of materials and structural status. Many advanced sensors have also been investigated for implementing real-time structural monitoring, such as wireless sensor networks, fiber optic sensors, etc. Fiber optic sensors are powerful tools for structural monitoring. FBG sensors are successfully deployed in many fields. However, these sensors are carefully prepared to be used properly for various needs. Distributed fiber optic sensors can sense strain, temperature, vibration, and acoustics through one sensing optical fiber line. At present, the spatial resolution of these sensors is accomplished at a sub-centimeter range, which can be used to detect cracks on materials. This Special Issue of Applied Science, "Structural Monitoring Using Advanced NDT techniques", will provide recent achievements in structural monitoring and materials characterization using advanced NDT techniques. In addition, this Issue will include some papers presented in WCNDT (World Conference on Non-Destructive-testing) 2020. Your contribution is welcome and much appreciated as an author or a reviewer.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
