Passive THz human body security inspection technology to solve human security problems

At the inauguration ceremony of the US President’s cost of 100 million U.S. dollars in security, in order to prevent terrorist attacks, the Department of Safety has introduced several sets of passive terahertz human imaging security inspection systems to make up for the shortcomings of traditional X-ray machines and explosives close-range detection. At the ceremony, the terahertz system also fully utilized its advantages of 3-15 meters long distance security screening, dynamic imaging, and concealed security screening of equipment and equipment. It minimized the danger to the greatest extent and ensured the smooth circulation of people. After the ceremony, the industry people also realized the superiority of this passive terahertz human imaging security system, and it is bound to become the sword to solve the current security problems.

Counter-terrorism just needs to drive security inspection products forward

Terrorism has become an important factor affecting world peace and development and it is the common enemy of all mankind. At present, violent terrorist incidents targeting China have frequently occurred and pose a serious threat to China’s national security and people’s lives and property.

The Anti-Terrorism Law of the People's Republic of China implemented on January 1, 2016, Article 34. The organizers of large-scale events and the management units of key objectives shall, in accordance with regulations, enter large-scale event venues, airports, railway stations, and docks. Employees, articles, and vehicles of key targets such as urban rail transit stations, long-distance bus terminals, and ports will undergo safety inspections. The discovery of contraband and controlled articles should be detained and reported to the authorities immediately. If any suspects are found to be suspected of illegal or criminal activities, they should immediately report to the authorities.

Article 35 For public transport vehicles such as aircraft, trains, ships, urban rail vehicles, and public electric vehicles, the operating organization shall be equipped with security personnel and corresponding equipment and facilities in accordance with regulations, and strengthen safety inspection and security.

The Chinese government attaches great importance to the investment in the public safety field, and vigorously supports the high-tech public safety technology. The demand for security inspection systems and equipment is increasing. The system equipment in the field of security inspection also presents a diversified and professional development trend as user needs continue to develop.

The traditional safety inspection equipment is frequently seen

Detection of hidden objects in the human body has been a hot issue at home and abroad. Currently, hidden object detection devices mainly include optical/infrared imagers, X-ray systems, CT detection systems, metal security doors, and hand-held metal detectors.

Although optics, X-ray systems, and infrared imaging have very high resolution, optical/infrared detection cannot penetrate clothes and coatings to detect concealed contraband; X-ray systems and CT detection systems provide excellent penetration , but its high radiation can harm the human body and can not be used for human body security; metal security doors can only alarm can not be located, and can not do for non-metallic contraband; hand-held metal detectors can not detect non-metallic prohibited items, and must contact operation The slow detection speed can easily cause the inspected person to be invaded.

New Technology - Crack Security Puzzle

So, is there a technology that can quickly identify all kinds of dangerous goods and it is harmless to the human body? Passive THz human security instrument is currently the world's leading technology to solve security problems.

Terahertz human body security technology - The use of terahertz waves for the daily penetration of special materials (cotton, hemp, chemical fiber, etc.) fills the gap in the field of human security, and is an important supplement to the current human body security measures.

Terahertz refers to the frequency of 0.1~10 THz in the electromagnetic spectrum, and the wavelength range is 0.03~3mm, which is between the radio wave and the light wave. Passive THz instrument is mainly used to detect the temperature difference between human body and objects. In the entire process, the terahertz security instrument does not radiate electromagnetic waves but passively receives terahertz waves emitted by the human body.

Therefore, it is the safest and most effective method in the field of security inspection. Because the energy released by terahertz is very small, it will not produce harmful photoionization in the human body.

How Does the Terahertz Security Detection System Protect Privacy?

Passive terahertz technology is different from active detection in that it cannot detect details of human physiological characteristics and does not infringe the privacy of the person being tested. Passive detection, that is, without the need for personnel to cooperate with the detection, the device to complete the detection of passing population. Further, when the installation of the device is started, it automatically detects the passing person in the 120-degree detection angle, and at the same time transmits the detected image information in real time on the back-end screen. If the person in the examined body carries items, the background screen image The display area will be marked with a rectangular box on a part of the human body to inform or prompt the security personnel to be carried by a certain part of the prober's body.

For special populations or special situations, the people being surveyed may not know that they are undergoing safety inspections. This will allow security personnel to better complete inspections of target groups and reduce the concerns and complaints of the individuals being inspected.

It is worth mentioning that since the entire security inspection process completely depends on the equipment for comprehensive inspection, the user does not need to deploy staff on the security inspection process. For this reason, the application of this equipment can greatly reduce the number of security personnel deployed. It is the door that opened the era of human security inspection 2.0; on the other hand, the entire process of the security inspection hardly takes time. Therefore, it is very suitable for public places such as airports, train stations, bus stations, shopping malls, etc., as well as government departments and important conferences. And special events such as large-scale events.

solution

1) Plug and play, compact size. Easy to install, can be hung from the ceiling, easy to hide;

2) Lighter weight, easier to move, more deployable; low power consumption (130W), can be used with battery

3) It is safe and harmless, does not infringe on human privacy, and does not harm the pacemaker wearers, infirm persons, pregnant women, magnetic media and other electronic devices;

4) Continuous real-time inspections can be performed at different distances, with a visible range of 3-15 meters;

5) Multiple devices can be used in combination to view images received by all devices through a single computer;

Metal and non-metal detection

1) Various weapons, simulation weapons, ammunition and explosives;

2) National currency, foreign currency, counterfeit currency and forged securities;

3) print, film, photos, records, videos, tapes, video tapes, laser discs, computer storage media and other items;

4) All kinds of strong poisons and drugs (liquid or powder);

5) Precious cultural relics and other prohibited styles;

6) Tobacco, alcohol, cosmetics, food, pharmaceutical electronic products;
