The reconstructed image can be obtained by the deconvolution of the detected image. Usually a Wiener filter is used for the reconstruction. The limitation of the Wiener filter is that it will introduce a significant distortion when the detected image contains noise. On the other hand, heuristic methods can obtain clear reconstructed image from noisy penumbral images. However, it significantly takes computation time. We proposed a new reconstruction method in the penumbral imaging to obtain clear reconstructed image by combining the multiple Wiener filters and the method can reduce computation time. The effectiveness of the proposed method has been demonstrated by computer simulation and real laser plasma experiment.","subitem_description_type":"Other"},{"subitem_description":"\u8ad6\u6587","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"en","subitem_1522300316516":"The Japan Society of Plasma Science and Nuclear Fusion Research"},{"subitem_1522300295150":"ja","subitem_1522300316516":"\u4e00\u822c\u793e\u56e3\u6cd5\u4eba\u30d7\u30e9\u30ba\u30de\u30fb\u6838\u878d\u5408\u5b66\u4f1a"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/46087"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"1880-6821"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"en","subitem_1522650091861":"Plasma and Fusion Research"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2011","bibliographicIssueDateType":"Issued"},"bibliographicPageEnd":"2406071-4","bibliographicPageStart":"2406071-1","bibliographicVolumeNumber":"6"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_1522306287251":{"subitem_1522306382014":"DOI","subitem_1522306436033":"https://doi.org/10.1585/pfr.6.2406071"}},{"subitem_1522306287251":{"subitem_1522306382014":"DOI","subitem_1522306436033":"https://doi.org/10.1585/pfr.6.2406071"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"6_2406071.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2012473/files/6_2406071.pdf"},"version_id":"ba4aaad4-9d65-4491-aa2f-d002689545e6"}]},"item_title":"Fast and Robust Reconstruction of Penumbral Images by Combining Multiple Wiener Filters","item_type_id":"15","owner":"1","path":["1642838338003","1642838406845"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-06-09"},"publish_date":"2020-06-09","publish_status":"0","recid":"2012473","relation_version_is_last":true,"title":["Fast and Robust Reconstruction of Penumbral Images by Combining Multiple Wiener Filters"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-10-31T07:03:05.434739+00:00"}
