We investigated the application of compressed sensing to digital holography to reconstruct object waves with high resolution from a single hologram. In the proposed method, the recording process of the hologram in off-axis optics is formulated as a linear transformation, and a compressive sensing-based object wave reconstruction method is introduced to reconstruct the high-resolution object waves. We also formulated the holographic tomography as a process of scattering from the three-dimensional scattering density distribution and interference with the reference light. We proposed holographic particle tracking velocimetry for microfluidics as an application of holographic tomography.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：若手研究; 研究期間：2019～2021; 課題番号：19K15466; 研究分野：光工学; 科研費の分化・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ(WEKO2)","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"YOSHIDA, Shuhei"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学理工学部; 講師"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉田, 周平"},{"creatorName":"ヨシダ, シュウヘイ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-12-05"}],"displaytype":"detail","filename":"19K15466seika.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"19K15466seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/23343/files/19K15466seika.pdf"},"version_id":"b3d404fa-5cfc-4f19-8338-8b0f470b1df7"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ディジタルホログラフィ","subitem_subject_scheme":"Other"},{"subitem_subject":"デジタルホログラフィ","subitem_subject_scheme":"Other"},{"subitem_subject":"圧縮センシング","subitem_subject_scheme":"Other"},{"subitem_subject":"3次元計測","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":"圧縮センシングとデジタルホログラフィの融合による高感度・高分解能3次元計測の実現","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"圧縮センシングとデジタルホログラフィの融合による高感度・高分解能3次元計測の実現","subitem_title_language":"ja"},{"subitem_title":"Fusion of Compressive Sensing and Digital Holography for High-Sensitivity, High-Resolution 3D Measurements","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4819"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-12-05"},"publish_date":"2022-12-05","publish_status":"0","recid":"23343","relation_version_is_last":true,"title":["圧縮センシングとデジタルホログラフィの融合による高感度・高分解能3次元計測の実現"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-08-02T06:45:07.358615+00:00"}
