金属探测器的工作原理
How Metal Detectors Work？
提到金属探测器这个词，你会从不同的人那里得到完全不同的反应。例如，有些人想在海滩上寻找硬币或埋藏的宝藏。其他人会想到机场安检，或者音乐会或运动会上的手持金属探测器。
Mention the words metal detector and you'll get completely different reactions from different people. For instance, some people think of combing a beach in search of coins or buried treasure. Other people think of airport security, or the handheld scanners at a concert or sporting event.
事实上，所有这些场景都是有效的。金属探测技术是我们生活中的一个重要组成部分，其应用范围从休闲到工作再到安全。机场、办公楼、学校、政府机构和监狱中的金属探测器有助于确保没有人携带武器进入房地。面向消费者的金属探测器为全世界数百万人提供了一个发现隐藏宝藏（以及大量垃圾）的机会。
The fact is that all of these scenarios are valid. Metal-detector technology is a huge part of our lives, with a range of uses that spans from leisure to work to safety. The metal detectors in airports, office buildings, schools, government agencies and prisons help ensure that no one is bringing a weapon onto the premises. Consumer-oriented metal detectors provide millions of people around the world with an opportunity to discover hidden treasures (along with lots of junk).
在本文中，您将了解金属探测器及其使用的各种技术。我们的重点将放在消费型金属探测器上，但大多数信息也适用于安装型的探测系统，如机场使用的探测系统，以及手持金属探测器。
In this article, you'll learn about metal detectors and the various technologies they use. Our focus will be on consumer metal detectors, but most of the information also applies to mounted detection systems, like the ones used in airports, as well as handheld security scanners.
