In the proposed sensor design, a sensing fiber with an inscribed high-order Bragg grating is attached to the observed metal surface. A broadening of high-order Bragg grating spectral characteristics is observed and used to detect small and highly localized longitudinal strain variations that occur along the fiber as a result of corrosive rust flakes\u2019 formations beneath the sensing fiber. The proposed approach provides a straightforward fabrication method, the possibility for unobtrusive mounting, including mounting of the sensor beneath the corrosion-protective layers, and consistent corrosion detection yields.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">July 2023<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.researchgate.net\/journal\/Structural-Control-and-Health-Monitoring-1545-2263?_tp=eyJjb250ZXh0Ijp7InBhZ2UiOiJwdWJsaWNhdGlvbiIsInByZXZpb3VzUGFnZSI6bnVsbH19\">Structural Control and Health Monitoring<\/a> 2023:1-14<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">DOI: <a rel=\"noreferrer noopener\" href=\"https:\/\/doi.org\/10.1155\/2023\/9972511\" target=\"_blank\">10.1155\/2023\/9972511<\/a><\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"677\" data-id=\"1359\" src=\"\/leoss\/wp-content\/uploads\/sites\/2\/2026\/03\/a-Strain-distribution-within-the-center-of-the-fiber-core-in-a-direction-which-is.jpg\" alt=\"\" class=\"wp-image-1359\" srcset=\"https:\/\/au.jovo.cc\/leoss\/wp-content\/uploads\/sites\/2\/2026\/03\/a-Strain-distribution-within-the-center-of-the-fiber-core-in-a-direction-which-is.jpg 600w, https:\/\/au.jovo.cc\/leoss\/wp-content\/uploads\/sites\/2\/2026\/03\/a-Strain-distribution-within-the-center-of-the-fiber-core-in-a-direction-which-is-266x300.jpg 266w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/figure>\n<\/figure>\n","protected":false},"excerpt":{"rendered":"<p>This paper presents a fiber optic sensor for the detection of corrosion processes that occur on metal surfaces.
