Lamb wave lunched in the glass around 2 MHz is imaged by the strobe photo elastic method introducing sensitive tint method. Ultrasonic wave field image that were processed with integration, subtraction and normalization was obtained to develop the contrast of image. In the sensitive tint image, the sound pressure polarity of the Lamb wave are indicated by red and blue, respectively. Using RGB data of S1 and A1 images, phase velocity versus frequency is analyzed to the wavenumber by the FFT to obtain the ultrasonic Lamb wave velocity. The agreement between the experiment and the analysis result revealed that this method can quantitatively measure the ultrasonic Lamb wave velocity.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"一般社団法人 日本画像学会"}]},"item_10001_relation_12":{"attribute_name":"NII論文ID NAID","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"130007497320","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.11370/isj.57.525","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA1137305X","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1344-4425","subitem_source_identifier_type":"ISSN"}]},"item_10001_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"秋田大学　理工学研究科"}]},"item_10001_version_type_20":{"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":"今野, 和彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"IMANO, Kazuhiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-11-07"}],"displaytype":"detail","filename":"57-525-2.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"riA_2019_5","url":"https://air.repo.nii.ac.jp/record/3817/files/57-525-2.pdf"},"version_id":"2444fae9-be22-47b0-8d19-54e0b383196c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ストロボ光弾性法","subitem_subject_scheme":"Other"},{"subitem_subject":"鋭敏色法","subitem_subject_scheme":"Other"},{"subitem_subject":"超音波画像","subitem_subject_scheme":"Other"},{"subitem_subject":"波数解析","subitem_subject_scheme":"Other"},{"subitem_subject":"位相速度","subitem_subject_scheme":"Other"},{"subitem_subject":"Strobe photo elastic method","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Sensitive tint method","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Ultrasonic sound imaging","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Wavenumber analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Phase velocity","subitem_subject_language":"en","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"鋭敏色法による固体中のLamb波伝搬画像からの超音波速度の定量計測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"鋭敏色法による固体中のLamb波伝搬画像からの超音波速度の定量計測"}]},"item_type_id":"10001","owner":"18","path":["630"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-11-07"},"publish_date":"2019-11-07","publish_status":"0","recid":"3817","relation_version_is_last":true,"title":["鋭敏色法による固体中のLamb波伝搬画像からの超音波速度の定量計測"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-25T11:15:02.706059+00:00"}
