Review of X-ray Security Inspection Technology

摘要: 近年来,X射线安全检查技术受到航空安全等需要的驱使,得到迅速发展。本文对国内外现有的用X射线探测行李中的爆炸物和其他违禁品的几个主要方法做了一个回顾,阐述了用单能法、双能法、双视角、散射、计算机断层成像法和立体匹配分层成像法进行物质识别的基本原理,并对各种方法的优缺点作了比较和讨论,最后对X射线安全检查技术的未来发展前景进行了展望。

Abstract: In these years, x-ray security inspection technology is developing rapidly due to the needs of airport security. This paper reviews the main techniques of using x-ray to inspect exploder and other contraband. It describes the methods of material recognition in single energy system, dual energy system, dual view system, scatter system, CT and stereo matching technique. Then we make a discussion and comparison among these methods. Lastly it gives foreground of the x-ray security inspection technology.
