摘　　要：硬X射线能带 (2 0KeV～ 1MeV)是我们了解天体物理中高能辐射过程的一个好窗口。成像硬X射线望远镜可以提供更好的分辨率和灵敏度来研究硬X射线天体物理学。本文介绍了成像硬X射线望远镜在美国和欧洲的发展 ,这包括 :1 )EXITE2 ,由美国哈佛———史密松林天体物理中心设计和运行的一个光电开关成像硬X射线望远镜 ;2 )EXIST ,一个成像硬X射线全天巡天望远镜 ,将于 2 0 1 0年由ULDB (EXIST -LINE)或国际空间站 (EXIST -ISS)承载 ;3)HERO ,由NASA/MSFC建造的一个新的硬X射线光学仪器。The hard X-ray (20 keV up to 1 MeV) energy band is a good window for us to learn the high energy radiation processes in astrophysics.The imaging hard X-ray telescopes provide better resolution and sensitivity for studying hard X-ray astrophysics.In this paper,the recent years developments of imaging hard X-ray telescopes in United States and Europe are introduced,including 1)EXITE2-a phoswich imaging hard X-ray telescope designed and operated by Harvard-Smithsonian Center for Astrophysics (CFA);2) EXIST - an imaging hard X-ray all-sky survey,which will be carried by ULDB (EXIST-LITE) or mounted on international space station (EXIST-ISS) in the year of 2010 and 3) HERO - a newly developed hard X-ray optics instrument,built by NASA/MSFC.
