An impact can produce microscopic fissures that could evolve into fractures or even the total collapse of the structure, so it is important to know the location and severity of each impact. For this purpose, optical fibers with Bragg gratings are used to analyze each impact and the vibrations generated by them. In this paper it is proven that optical fibers with Bragg gratings can be used to detect impacts, and also that a high-frequency interrogator is necessary to collect valuable information about the impacts. The use of two interrogators constitutes the main novelty of this paper.<\/jats:p>","DOI":"10.3390\/s130911998","type":"journal-article","created":{"date-parts":[[2013,9,9]],"date-time":"2013-09-09T12:02:47Z","timestamp":1378728167000},"page":"11998-12011","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Proof of Concept of Impact Detection in Composites Using Fiber Bragg Grating Arrays"],"prefix":"10.3390","volume":"13","author":[{"given":"Javier","family":"Gomez","sequence":"first","affiliation":[{"name":"Department of Communications Engineering, Faculty of Engineering,  University of the Basque Country, Alda Urquijo, s\/n.
