In this work, we perform a proof-of-concept demonstration of a chirp modulation scheme to extend the measurement range of BOCDR. In this scheme, optical frequency is modulated using a chirp-shaped waveform. We show that, although the spatial resolution is slightly deteriorated, the measurement range and the range-to-resolution ratio can be relatively largely improved. In our preliminary experiment, the range-to-resolution ratio is 471, which is approximately 3 times higher than that of a standard configuration, proving the effectiveness of this scheme.","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP Science"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.35848/1882-0786/aba151","subitem_relation_type_select":"DOI"}}]},"item_2_relation_44":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://doi.org/10.35848/1882-0786/aba151"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.35848/1882-0786/aba151","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12295133","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18820778","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Institute of Innovative Research, Tokyo Institute of Technology & Faculty of Engineering, Yokohama National University"},{"subitem_text_value":"College of Engineering, Shibaura Institute of Technology"},{"subitem_text_value":" Institute of Innovative Research, Tokyo Institute of Technology"},{"subitem_text_value":"Faculty of Engineering, Yokohama National University"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kohei, Noda"}],"nameIdentifiers":[{"nameIdentifier":"37593","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Heeyoung, Lee"}],"nameIdentifiers":[{"nameIdentifier":"37594","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kentaro, Nakamura"}],"nameIdentifiers":[{"nameIdentifier":"37595","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yosuke, Mizuno"}],"nameIdentifiers":[{"nameIdentifier":"37596","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"30630818","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=30630818"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-07-08"}],"displaytype":"detail","filename":"APEX_13_082003.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"APEX_13_082003.pdf","url":"https://ynu.repo.nii.ac.jp/record/10708/files/APEX_13_082003.pdf"},"version_id":"1ede4f5c-cf85-4e95-81a8-41f4236ff4e6"}]},"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":"Measurement range enlargement in Brillouin optical correlation-domain reflectometry based on chirp modulation scheme","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Measurement range enlargement in Brillouin optical correlation-domain reflectometry based on chirp modulation scheme"}]},"item_type_id":"2","owner":"3","path":["496"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-09-10"},"publish_date":"2020-09-10","publish_status":"0","recid":"10708","relation_version_is_last":true,"title":["Measurement range enlargement in Brillouin optical correlation-domain reflectometry based on chirp modulation scheme"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T17:42:59.086534+00:00"}
