The method uses a digital filter that effectively becomes a sinc filter utilizing the orthogonality of trigonometric functions by multiplication of the acquired data by a trigonometric function. The computational time of the method to compute the signal from n points of data is O(n), whereas the time with Fourier transform is O(n log n). We confirm our method with a large detection volume of the ensemble NV centers. Consequently, we obtained a DC magnetic field sensitivity of 2.4 nT/√Hz.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"第４回QST国際シンポジウム","subitem_description_type":"Other"}]},"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":"Masuyama, Yuta"}],"nameIdentifiers":[{"nameIdentifier":"914714","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohshima, Takeshi"}],"nameIdentifiers":[{"nameIdentifier":"914715","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masuyama, Yuta","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"914716","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohshima, Takeshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"914717","nameIdentifierScheme":"WEKO"}]}]},"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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Digital signal processing for portable highly sensitive diamond quantum magnetometer","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Digital signal processing for portable highly sensitive diamond quantum magnetometer"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-01-04"},"publish_date":"2021-01-04","publish_status":"0","recid":"81515","relation_version_is_last":true,"title":["Digital signal processing for portable highly sensitive diamond quantum magnetometer"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:59:46.076524+00:00"}
