中文摘要 | 自從1980年代初起,編碼板成像技術已廣泛應用於硬X射線與γ射線成像望遠鏡上,相較於用在軟X射線,以X射線光學方法的成像望遠鏡而言,使用編碼板成像技術的望遠鏡有更大的頻寬、視場與有效面積。本文將介紹編碼板的基本原理與利用互相關的方法成像過程,在應用在天文望遠鏡部分,對於編碼板的選擇、資料處理,以及利用編碼板成像技術成像望遠鏡的優勢、困難與展望等議題也在本文中予以討論。 |
英文摘要 | Coded aperture mask technique to image the hard X-ray and γ-ray sky has been adopted to many X-ray telescopes since early 80's. In comparison to X-ray optics for soft X-ray, the telescopes using coded mask technique may have wider bandwidth, larger field of view and effective area. This article introduces the basic principle of coded aperture mask and how to recover the original image with cross correlation method. Its applications to astronomical telescopes, including selection of mask and data reduction, as well as the vantages, limitations and prospects of coded aperture mask telescopes are also discussed. |
