高能天体物理中的编码孔径成像

Coded Aperture Imaging in High-Energy Astrophysics

João Braga

摘要:

在过去的几十年里,硬X射线和低能伽马射线编码孔径成像仪器作为高能探测器和瞬态源发现者和跟踪者已经非常成功。尽管与聚焦仪器相比,编码孔径望远镜的灵敏度相对较低,但它仍然是在大源场中对单个点源进行同步、高节奏光谱测量的一个非常好的选择。本文介绍了高能天体物理中编码孔径成像仪器的基本原理。重点是基本方面的技术,编码掩模仪器的特点,和属性的重建图像。

英文摘要:

Hard X-ray and low-energy gamma-ray coded-aperture imaging instruments have been highly successful as high-energy surveyors and transient-source discoverers and trackers over the past decades. Albeit having relatively low sensitivity as compared to focussing instruments, coded-aperture telescopes still represent a very good choice for simultaneous, high cadence spectral measurements of individual point sources in large source fields. Here I present a review of the fundamentals of coded-aperture imaging instruments in high-energy astrophysics. Emphasis is on fundamental aspects of the technique, coded-mask instrument characteristics, and properties of the reconstructed images.
