The sensor probe comprises a single mode fiber (SMF) that is inserted into a ceramic tube terminated by an ultra-thin gold film. The probe performs with an excellent UW sensitivity thanks to the nanolayer gold film, and thus is capable of detecting a weak UW in air medium. Furthermore, the compact sensor is a symmetrical structure so that it presents a good directionality in the UW detection. The spectral band-side filter technique is used for UW interrogation. After scanning the models using the sensing probe in air, the two-dimensional (2D) images of four physical models are reconstructed.<\/jats:p>","DOI":"10.3390\/s17020397","type":"journal-article","created":{"date-parts":[[2017,2,17]],"date-time":"2017-02-17T12:10:34Z","timestamp":1487333434000},"page":"397","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["UW Imaging of Seismic-Physical-Models in Air Using Fiber-Optic Fabry-Perot Interferometer"],"prefix":"10.3390","volume":"17","author":[{"given":"Qiangzhou","family":"Rong","sequence":"first","affiliation":[{"name":"Physics Department, Northwest University, No.229, Taibai Road (North), Xi\u2019an 710069, China"}]},{"given":"Yongxin","family":"Hao","sequence":"additional","affiliation":[{"name":"Physics Department, Northwest University, No.229, Taibai Road (North), Xi\u2019an 710069, China"}]},{"given":"Ruixiang","family":"Zhou","sequence":"additional","affiliation":[{"name":"Physics Department, Northwest University, No.229, Taibai Road (North), Xi\u2019an 710069, China"}]},{"given":"Xunli","family":"Yin","sequence":"additional","affiliation":[{"name":"Physics Department, Northwest University, No.229, Taibai Road (North), Xi\u2019an 710069, China"}]},{"given":"Zhihua","family":"Shao","sequence":"additional","affiliation":[{"name":"Physics Department, Northwest University, No.229, Taibai Road (North), Xi\u2019an 710069, China"}]},{"given":"Lei","family":"Liang","sequence":"additional","affiliation":[{"name":"Physics Department, Northwest University, No.229, Taibai Road (North), Xi\u2019an 710069, China"}]},{"given":"Xueguang","family":"Qiao","sequence":"additional","affiliation":[{"name":"Physics Department, Northwest University, No.229, Taibai Road (North), Xi\u2019an 710069, China"}]}],"member":"1968","published-online":{"date-parts":[[2017,2,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1788","DOI":"10.1190\/1.1444863","article-title":"Estimation of fracture parameters from reflection seismic data-Part I: HTI model due to a single fracture set","volume":"65","author":"Bakulin","year":"2000","journal-title":"Geophysics"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"WC123","DOI":"10.1190\/geo2011-0514.1","article-title":"Targeting nickel sulfide deposits from 3D seismic reflection data at Kambalda, Australia","volume":"77","author":"Urosevic","year":"2012","journal-title":"Geophysics"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"505","DOI":"10.1130\/GES00961.1","article-title":"P-wave tomography of potential convective downwellings and their source regions, Sierra Nevada, California","volume":"10","author":"Jones","year":"2014","journal-title":"Geosphere"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"WA233","DOI":"10.1190\/geo2015-0176.1","article-title":"A rock-physics investigation of unconsolidated saline permafrost: P-wave properties from laboratory ultrasonics measurements","volume":"81","author":"Dou","year":"2016","journal-title":"Geophysics"},{"key":"ref_5","doi-asserted-by":"crossref","first-page":"880","DOI":"10.1016\/j.ultras.2012.02.010","article-title":"Standing wave brass-PZT square tubular ultrasonics motor","volume":"52","author":"Park","year":"2012","journal-title":"Ultrasonics"},{"key":"ref_6","first-page":"1205","article-title":"Intrinsic Stress Control of Sol-Gel Derived PZT Films for Buckled Diaphragm Structures of Highly Sensitive Ultrasonics Microsensors","volume":"120","author":"Yamashita","year":"2015","journal-title":"Eurosensors"},{"key":"ref_7","doi-asserted-by":"crossref","first-page":"114","DOI":"10.1016\/j.ast.2016.04.014","article-title":"A health management technology for multisite cracks in an in-service aircraft fuselage based on multi-time-frame laser ultrasonics energy mapping and serially connected PZTs","volume":"54","author":"Bae","year":"2016","journal-title":"Aerosp.
