FBG sensors used for multipoint sensing generally employ wavelength division multiplexing techniques utilizing several Bragg central wavelengths; by contrast, the DTR 3 interrogator uses a continuous pulse array based on a pseudorandom number code and a long-gauge FBG utilizing a single Bragg wavelength and composed of simple hardware devices. The DTR 3 scheme can detect distributed strain at a 50 cm spatial resolution using a long-gauge FBG with a 100 Hz sampling rate. We evaluated the strain sensing characteristics of the long-gauge FBG when attached to a 2.5 m aluminum bar and a 5.5 m helicopter blade model, determining these structure natural frequencies in free vibration tests and their distributed strain characteristics in static tests.","subitem_description_type":"Other"}]},"item_7_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: 図版あり","subitem_description_type":"Other"}]},"item_7_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains illustrations","subitem_description_type":"Other"}]},"item_7_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: PA1520012000","subitem_description_type":"Other"}]},"item_7_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Optical Society of America"}]},"item_7_relation_25":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"info:doi/10.1364/AO.54.001191"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1364/AO.54.001191","subitem_relation_type_select":"DOI"}}]},"item_7_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1559-128X","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00543409","subitem_source_identifier_type":"NCID"}]},"item_7_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"創価大学工学部"},{"subitem_text_value":"宇宙航空研究開発機構航空本部(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構航空本部(JAXA)"},{"subitem_text_value":"首都大学東京航空宇宙工学"}]},"item_7_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Faculty of Engineering, Soka University"},{"subitem_text_language":"en","subitem_text_value":"Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Department of Aerospace Engineering, Tokyo Metropolitan University"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"西山, 道子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"井川, 寛隆"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"葛西, 時雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"渡辺, 直行"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nishiyama, Michiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Igawa, Hirotaka","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kasai, Tokio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Watanabe, Naoyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Distributed strain measurement based on long-gauge FBG and delayed transmission/reflection ratiometric reflectometry for dynamic structural deformation monitoring","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Distributed strain measurement based on long-gauge FBG and delayed transmission/reflection ratiometric reflectometry for dynamic structural deformation monitoring","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["1888"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-10-16"},"publish_date":"2015-10-16","publish_status":"0","recid":"22599","relation_version_is_last":true,"title":["Distributed strain measurement based on long-gauge FBG and delayed transmission/reflection ratiometric reflectometry for dynamic structural deformation monitoring"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:18:24.409413+00:00"}
