Promotion of combustion is related to \nin-cylinder gas flow. There is laser doppler velocimetry (LDV) in one of equipment to measure \nin-cylinder gas flow. We changed light source from gas laser of large size to laser diode (LD) of small \nsize for miniaturization to improve in flexibility. LD light has an extension angle different in vertical and \nhorizontal direction, therefore beam section becomes elliptic section. There is possibility that beam \npower cannot be fully used by this cause. Then, in this research, we studied about the way of collimation \nto use beam power efficiently. As a result, we found the way of collimation to reduce beam diameter and \nincrease beam strength. But, this way caused decline of S/N due to increase of noise. Then, when we \nmeasured with frequency shifter, we were not possible to measure in-cylinder gas flow, and more \nexamination should be required.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宮崎大学工学部","subitem_publisher_language":"ja"},{"subitem_publisher":"Faculty of Engineering, University of Miyazaki","subitem_publisher_language":"en"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00732558","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05404924","subitem_source_identifier_type":"ISSN"}]},"item_10002_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":"田坂, 英紀","creatorNameLang":"ja"},{"creatorName":"タサカ, ヒデノリ","creatorNameLang":"ja-Kana"},{"creatorName":"Tasaka, Hidenori","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"安達, 祐二"},{"creatorName":"アダチ, ユウジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Adachi, Yuji","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":"2020-06-21"}],"displaytype":"detail","filename":"KJ00003579381.pdf","filesize":[{"value":"742.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00003579381.pdf","url":"https://miyazaki-u.repo.nii.ac.jp/record/2419/files/KJ00003579381.pdf"},"version_id":"c2821ba9-23ce-4d75-99fa-f7d4526585f5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Internal combustion engine, In-cylinder gas flow, Laser doppler velocimetry (LDV), Laser diode (LD), Collimation","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"LD-LDVの光源光学系の改善","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"LD-LDVの光源光学系の改善","subitem_title_language":"ja"},{"subitem_title":"Improvement of Light Source Optics of LD-LDV","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"5","path":["73","36","330","315"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-06-28"},"publish_date":"2007-06-28","publish_status":"0","recid":"2419","relation_version_is_last":true,"title":["LD-LDVの光源光学系の改善"],"weko_creator_id":"5","weko_shared_id":2},"updated":"2023-07-29T23:29:21.203140+00:00"}
