This method uses the correlation between a launched pseudorandom noise code signal and its reflection enabling simultaneous measurement at many points along the optical fiber in real time with a high signal-to-noise ratio. In a light intensity-based experiment with an 850-nm LED, the tested three hetero-core optical fiber hydrogen tip sensors proved to be reproducible responses with and without hydrogen absorption, with showing the similar time response and sensitivity compared with those of our previously reported sensor. Multipoint hydrogen detection was demonstrated using four SPR hydrogen tip sensors. Our experimental results showed that four sensors using the 25 nm Au/60 nm Ta2O5/5 nm Pd multilayer film exhibited a response time of ～ 25 s for a 4% hydrogen concentration. In addition, it was found that all sensors can detect the hydrogen concentration with sufficient sensitivities in real time.","subitem_description_type":"Other"}]},"item_7_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_7_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_7_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: PA1620054000","subitem_description_type":"Other"}]},"item_7_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"IEEE"}]},"item_7_relation_25":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"info:doi/10.1109/JSEN.2016.2518701"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1109/JSEN.2016.2518701","subitem_relation_type_select":"DOI"}}]},"item_7_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1530-437X","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":"AA11551238","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"},{"subitem_text_value":"創価大学"},{"subitem_text_value":"宇宙航空研究開発機構航空本部(JAXA)"},{"subitem_text_value":"創価大学"}]},"item_7_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Soka University"},{"subitem_text_language":"en","subitem_text_value":"Soka University"},{"subitem_text_language":"en","subitem_text_value":"The Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Soka 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":"細木, 藍"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"西山, 道子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"井川, 寛隆"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"渡辺, 一弘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hosoki, Ai","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nishiyama, Michiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Igawa, Hirotaka","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Watanabe, Kazuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Fiber optic","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"hetero-core","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"hydrogen","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"palladium","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"tip structure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"multipoint","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"PN code correlation","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Multipoint Hydrogen Sensing of Hetero-Core Fiber SPR Tip Sensors With Pseudorandom Noise Code Correlation Reflectometry","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Multipoint Hydrogen Sensing of Hetero-Core Fiber SPR Tip Sensors With Pseudorandom Noise Code Correlation Reflectometry","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["1888"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-07-15"},"publish_date":"2016-07-15","publish_status":"0","recid":"22739","relation_version_is_last":true,"title":["Multipoint Hydrogen Sensing of Hetero-Core Fiber SPR Tip Sensors With Pseudorandom Noise Code Correlation Reflectometry"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:16:09.742210+00:00"}
