Comparing its characteristics with a pin hole camera with the same detector area, the signal to noise ratio is better in the case that spurious counts are predominant over the counts due to x-ray image. If the positional resolution of the position sensitive detector is poor, the reconstructed image is obscurred by just the same amount as the image that would be obtained by the pin hole camera with the same position sensitive detector. In the case that some parts of the detector mulfunctioned and some data are lost, X-ray image can be reconstructed by substituting the mean value of the observed data to the lost data. Even if an x-ray image can not be seen by some part of the detector, the x-ray image can be reconstructed by usual Hadamard transformation method. An Hadamard transform x-ray telescope is constructed and its operational features are investigated experimentally. The Hadamard mask is made by the photo etching technique. The rise time method proposed by Borkowski and Kopp is employed to get the positional information from the multiwire proportional counter. The HTXT functioned well and the results show the validity of this telescope in x-ray astronomy.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0125781000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学宇宙航空研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0563-8100","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00161914","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"大阪大学理学部"},{"subitem_text_value":"大阪大学理学部"},{"subitem_text_value":"大阪大学理学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"宮本, 重徳"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"常深, 博"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"津野, 克彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MIYAMOTO, Sigenori","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TSUNEMI, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TSUNO, Katsuhiko","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":"2020-01-24"}],"displaytype":"detail","filename":"SA0125781.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0125781.pdf","url":"https://jaxa.repo.nii.ac.jp/record/32498/files/SA0125781.pdf"},"version_id":"ce25e4ea-f4cf-429b-bc7e-b7a781353571"}]},"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":"<論文>Hadamard Transform X-ray Telescope","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"<論文>Hadamard Transform X-ray Telescope"}]},"item_type_id":"9","owner":"1","path":["1890","1910"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"32498","relation_version_is_last":true,"title":["<論文>Hadamard Transform X-ray Telescope"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:30:46.800723+00:00"}
