 Do you need a drink to pass the security check? This artifact to understand


With the approaching of the Import Fair, there are a lot of liquid and letters in the import and export goods. How can we make these goods which can not be drunk for inspection and dismantled for inspection pass through the country efficiently and safely?

The academician team of Zhuangsonglin of Shanghai University of Technology and Shanghai Customs have developed two artifacts - THz liquid detector and THz letter detector. Using the former to scan the bottle body lightly, the potential safety hazards of the liquid in the bottle can be judged within 0.1 seconds; using the latter to scan the alignment letter lightly, we can know whether there are dangerous substances such as mutated biological seeds, viruses, morphine and so on.

What is the principle of the two artifact?

According to experts, each substance has its own spectrum, just like human fingerprints, terahertz spectrum liquid detector, terahertz spectrum letter detector only need to sweep through non-destructive, non-invasive, non-contact way to distinguish different spectrum and quickly identify the type of substance, just like. Like fingerprint recognition.

This kind of security inspection method improves the accuracy of liquid and letter security inspection, and speeds up the on-site disposal rate. Compared with the traditional security detector, its compact shape is also conducive to cooperating with the security transmission line, does not need to be modified, saves space and is convenient to use. After the Import Expo, the terahertz spectrum liquid detector will be put into use in the peoples Square.

As a technology field, terahertz will be used not only for liquid and letter detection, but also for biology, radar and communication.

Terahertz spectrum liquid detector is a homemade principle machine of pure blood. It covers more than 70 patents from the whole system to terahertz chip and radiation antenna. We can confidently say that the original technology development of the science and technology terahertz system is at the forefront of the world. Academician Zhuang Songlin, Professor Zhu Yiming said. When the import fair is about to take place, what can universities do for the import fair? Zhu Yiming has his own understanding and persistence. He believes that colleges and universities are not enterprises, not companies, and it is inappropriate to enter the product and market fields. The duty of colleges and universities is to break the international blockade and monopoly of related technology by studying original technology and become the pioneer of technology. Only when schools solve the core technical problems urgently needed by the state, can enterprises and companies carry out high-level transformation of production and work hand in hand to achieve China Intelligent Manufacturing.
