金属探测器最早的发展始于20世纪20年代，是一种借助于传感器检测附近金属是否存在的电子仪器，常用于寻找隐藏的物体或埋在地下的金属物内的金属夹杂物。金属检测器的最简单的形式由一个的振荡器产生一个交变电流穿过线圈产生的交变磁场。如果一块导电金属接近线圈，涡流会感应出的金属，并将产生其自己的磁场。如果另一个线圈用于测量磁场（作为磁力计），由于磁场中的变化，该金属物体可以被检测到。随着晶体管、传感技术、集成电路以及电脑等技术的不断发展，金属探测器在设备精度、轻型化等实用性方面也有了显著的改进，同时其应用范围也有了进一步的拓展，目前广泛应用于金属探矿（测）、安检、工业探测等领域。

Initially originated in the 1920s, metal detector is an electronic instrument to detect the existing metal by virtue of sensor, used to search the metallic inclusions contained in the hidden objects or metal buried under earth. The simplest form of metal detector is an alternating magnetic ifeld made by alternating current through coil produced by oscillator. When a conductive metal approaches to a coil, eddy current will induce the metal and produce its magnetic ifeld. If another coil is used as magnetometer to measure magnetic ifeld, the metal will be detected due to the alternation of the magnetic ifeld. With the development of transistor, sensor technology, integrated circuit and computer, the equipment accuracy and light-weight trend of metal detector have been improved signiifcantly;meanwhile the application scope has been enlarged, including metal detection, security check and industrial detection.
