In this study, we investigate three methods to enhance the performance of a fiber optic strain measurement system. In the first method, we constructed a model of a Brillouin gain spectrum (BGS) shape generated in a fiber installed on ring structures, such as tunnels. Ring circumferential strain is obtained under the condition that the modeled BGS agrees well with the observed BGS. Next, we constructed another model based on the BGS shape under temporally nonuniform strain produced in oscillating structures. This model, similar to the first model, is used for extracting information about the temporally nonuniform strain. Lastly, a BGS observation method was investigated to improve the performance of the fiber optic strain measurement system. Two pulses with different widths were launched into the fiber and the difference of two BGSs generated by the pulses were analyzed.", "subitem_description_type": "Abstract"}]}, "item_8_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "2012年度～2015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": "24510225", "subitem_description_type": "Other"}]}, "item_8_full_name_2": {"attribute_name": "著者（ヨミ）", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "34040", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "ナルセ, ヒロシ", "nameLang": "ja-Kana"}]}, {"nameIdentifiers": [{"nameIdentifier": "34041", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "タテダ, ミツヒロ", "nameLang": "ja-Kana"}]}, {"nameIdentifiers": [{"nameIdentifier": "34042", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "ミシマ, ナオキ", "nameLang": "ja-Kana"}]}]}, "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"}]}, {"creatorNames": [{"creatorName": "立田, 光廣", "creatorNameLang": "ja"}]}, {"creatorNames": [{"creatorName": "三島, 直樹", "creatorNameLang": "ja"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-01-12"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "40K18194.pdf", "filesize": [{"value": "820.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 820500.0, "url": {"label": "40K18194", "url": "https://mie-u.repo.nii.ac.jp/record/11763/files/40K18194.pdf"}, "version_id": "f926f937-87c7-41de-8c1a-b0cf46615658"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "光ファイパセンサ", "subitem_subject_scheme": "Other"}, {"subitem_subject": "不均一ひずみ", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ブリルアンゲインスベクトル", "subitem_subject_scheme": "Other"}, {"subitem_subject": "形状解析", "subitem_subject_scheme": "Other"}, {"subitem_subject": "モデル", "subitem_subject_scheme": "Other"}, {"subitem_subject": "円環", "subitem_subject_scheme": "Other"}, {"subitem_subject": "パルス", "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": "分布型光ファイバひずみ計測の高性能化についての研究", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "分布型光ファイバひずみ計測の高性能化についての研究", "subitem_title_language": "ja"}, {"subitem_title": "The performance enhancement of distributed fiber optic strain measurements using Brillouin scattering", "subitem_title_language": "en"}]}, "item_type_id": "8", "owner": "15", "path": ["1692685140697"], "permalink_uri": "http://hdl.handle.net/10076/00017401", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2018-01-12"}, "publish_date": "2018-01-12", "publish_status": "0", "recid": "11763", "relation": {}, "relation_version_is_last": true, "title": ["分布型光ファイバひずみ計測の高性能化についての研究"], "weko_shared_id": -1}
