中国电子科技集团公司第38研究所研制完成的我国首台太赫兹安检仪,在8日开幕的第九届中国国际国防电子展览会上正式亮相。太赫兹是一种波长介于红外线与微波之间的电磁波,具有很强的穿透性,能够轻易穿透衣物,人体自身会产生这种电磁波并向外辐射。这台“博微太赫兹人体安检仪”就是通过被动接收人体发出的太赫兹波,经处理转换后,形成人体的二维太赫兹“快照”。当人所穿衣物中隐藏有物品时,吸收和阻拦了太赫兹波的正常轨迹,使得“快照”中对应物品所在的位置和人体背景之间产生强度对比,从而探知到物品的 The first terahertz security instrument developed in the 38th Institute of China Electronics Technology Group Corporation was officially unveiled at the Ninth China International Defense Electronics Exhibition opened on the 8th. Terahertz is an electromagnetic wave whose wavelength is between infrared and microwaves. It has strong penetrability and can easily penetrate clothing. The human body itself generates such electromagnetic waves and radiates outward. This set of “micro-micro-terahertz human security instrument ” is through the passive reception of terahertz waves emitted by the human body, after processing conversion, the formation of the human body two-dimensional terahertz “snapshot ”. When people wear clothing hidden items, the absorption and blocking the normal trajectory of terahertz waves, making “snapshot ” in the corresponding article location and the human body background intensity comparison, to detect the object
