However, it was indirect observation. It has been suggested that is a diode laser energy transmission system to supply a lunar rover for direct observation at the bottom of craters in the lunar polar region, where no sun light all the year and it is in a severe cold environment. A full-size model of a lunar rover using a laser energy transportation has been fabricated and 100 m energy transportation test has been successfully performed. The high power laser diodes commercially available are composed of about 20 small laser diode spots arranged in an array with a spacing of 250 micrometers. Each spot is about 1 micrometer x 100 micrometers and the beam divergence of 35 deg x 11 deg. The laser diode being used is also the same and an array of small micro-lenses are arranged in front of the spot array to obtain a parallel beam. For 100 m transmission, a micro-lens array in front of the laser diode spots is sufficient to get a beam divergence of 12 mrad x 12 mrad. In the actual lunar exploration, at least 5 km transmission is required. The rover shall receive with a solar panel of a size less than 1 m so that the beam divergence of 2 x 10(exp -4) rad is required. So a small emitting area laser diode must be used. These device are used on CD or DVD drive. The size of the emitting area is about 1 x 3 micrometers. It is useful to energy transportation, if a large number of the laser diode are used. Now here is a discussion that is long distance laser energy transmission(approximately 7 km) using small emitting area laser diode.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0045915018","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"The Institute of Space and Astronautical Science (ISAS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学 理工学部"},{"subitem_text_value":"近畿大学 理工学部"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Kinki University School of Science and Engineering"},{"subitem_text_language":"en","subitem_text_value":"Kinki University School of Science and Engineering"}]},"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":"武田, 和也"}],"nameIdentifiers":[{"nameIdentifier":"45248","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"河島, 信樹"}],"nameIdentifiers":[{"nameIdentifier":"45249","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takeda, Kazuya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"45250","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawashima, Nobuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"45251","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"レーザーパワー伝送","subitem_subject_scheme":"Other"},{"subitem_subject":"氷","subitem_subject_scheme":"Other"},{"subitem_subject":"ルナ・プロスペクター","subitem_subject_scheme":"Other"},{"subitem_subject":"月ローバー","subitem_subject_scheme":"Other"},{"subitem_subject":"極地域","subitem_subject_scheme":"Other"},{"subitem_subject":"レーザーダイオード","subitem_subject_scheme":"Other"},{"subitem_subject":"高パワーレーザー","subitem_subject_scheme":"Other"},{"subitem_subject":"太陽電池パネル","subitem_subject_scheme":"Other"},{"subitem_subject":"ビーム発散","subitem_subject_scheme":"Other"},{"subitem_subject":"研究開発","subitem_subject_scheme":"Other"},{"subitem_subject":"長距離伝送","subitem_subject_scheme":"Other"},{"subitem_subject":"エネルギー伝送","subitem_subject_scheme":"Other"},{"subitem_subject":"laser power transmission","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"water ice","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Lunar Prospector","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"lunar rover","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"polar region","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"laser diode","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"high power laser","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"solar cell panel","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"beam divergence","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"research and development","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"long distance transmission","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"energy transmission","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"月面氷探査車モデルへの100mレーザーエネルギー伝送と問題点","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"月面氷探査車モデルへの100mレーザーエネルギー伝送と問題点"}]},"item_type_id":"5","owner":"1","path":["1579","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"8168","relation_version_is_last":true,"title":["月面氷探査車モデルへの100mレーザーエネルギー伝送と問題点"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:27:25.204148+00:00"}
