In this study, we conducted some researches so that the systems become widely used.\nFirstly, we constructed the model expressing the shape of the Brillion gain spectrum (BGS) observed in an optical fiber in which nonuniform strains varying spatially and temporally are simultaneously produced. Secondly, we developed a method for measuring the circumferential strain in general ring-shaped structures. In this method, the model which has the unknown strain described by a Fourier series is fitted to the BGS observed in the optical fiber attached to the structures. In addition, we developed a method for measuring the displacement of each part of the structures. The structures are regarded as being composed of small beams and the displacement is calculated from strains in the beams.","subitem_description_type":"Abstract"}]},"item_8_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"2016年度～2019年度科学研究費補助金(基盤研究(C))研究成果報告書","subitem_description_type":"Other"}]},"item_8_description_64":{"attribute_name":"科研費番号","attribute_value_mlt":[{"subitem_description":"16K01286","subitem_description_type":"Other"}]},"item_8_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_8_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_8_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Kaken / 科研費報告書"}]},"item_8_version_type_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"成瀬, 央","creatorNameLang":"ja"},{"creatorName":"ナルセ, ヒロシ","creatorNameLang":"ja-Kana"},{"creatorName":"Naruse, Hiroshi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"三島, 直行","creatorNameLang":"ja"},{"creatorName":"ミシマ, ナオキ","creatorNameLang":"ja-Kana"},{"creatorName":"Mishima, Naoki","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-01-24"}],"displaytype":"detail","filename":"2021RP0080.pdf","filesize":[{"value":"2.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"2021RP0080","url":"https://mie-u.repo.nii.ac.jp/record/14546/files/2021RP0080.pdf"},"version_id":"7b3122d6-5e1d-4662-94b0-a4058f6031fb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"光ファイバセンシング","subitem_subject_scheme":"Other"},{"subitem_subject":"構造物","subitem_subject_scheme":"Other"},{"subitem_subject":"モニタリング","subitem_subject_scheme":"Other"},{"subitem_subject":"ブリルアンスペクトル","subitem_subject_scheme":"Other"},{"subitem_subject":"モデル","subitem_subject_scheme":"Other"},{"subitem_subject":"ひずみ","subitem_subject_scheme":"Other"},{"subitem_subject":"変位","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"光ファイバひずみ計測の普及に向けた計測の高精度化についての研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"光ファイバひずみ計測の普及に向けた計測の高精度化についての研究","subitem_title_language":"ja"},{"subitem_title":"Research on measurement accuracy improvement for widely using distributed fiber optic strain measurement","subitem_title_language":"en"}]},"item_type_id":"8","owner":"15","path":["1692685146800"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-01-24"},"publish_date":"2022-01-24","publish_status":"0","recid":"14546","relation_version_is_last":true,"title":["光ファイバひずみ計測の普及に向けた計測の高精度化についての研究"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-11-20T01:43:36.093661+00:00"}
