The terahertz wave is called the natural human security "black technology" because of its unique performance. The human body security device developed by this method also solves a problem in life: it is not only safer and more efficient to say goodbye to the cumbersome security check program. more reliable. The core sensor we use is 250GHz. It is a very small device. It is only the size of the mainframe and weighs 24Kg. The smaller the sensor, the smaller the size of the device. We are constantly upgrading and expanding its application. There will also be smaller devices coming out of the market. The story behind this security instrument is also the epitome of the development of terahertz security technology over the years.
After the security check, God does not know, ghosts do not know!
Imagine that at crowded stations, airports, important meetings, or concert security checkpoints, you no longer need to stop for manual inspections. You just have to walk through a seemingly ordinary passage to find out if you are carrying them. All kinds of contraband and dangerous goods such as metal, ceramics, powder, liquid, colloid, etc., thus greatly improving the efficiency of transportation under the premise of ensuring safety. Such high-tech scenes seem to be far away. In fact, they have been implemented in some important public security fields, and will be gradually applied to a wider range in the future.
Terahertz waves have high resolution, strong penetrability, safety, and substance identification.
Speaking of the terahertz human body security device, we must start with the terahertz wave.
"THz wave is an electromagnetic wave whose wavelength is between infrared and microwave. It can be generated by many things in nature and radiated outward." THz technical application expert, Zhuon Industrial Technology Chief Engineer, due to terahertz Waves are in the transitional zone between electronics and photonics, and there is no good means of detection. For a long time, people's understanding of terahertz waves is very limited, let alone development and application.
The reason why terahertz technology has attracted widespread attention in the scientific community is that the special position of the terahertz wave on the electromagnetic spectrum determines that it has many unique properties compared with electromagnetic waves of other frequencies.
“Terrah waves have higher resolution and higher resolution than microwaves; they are penetrable compared to visible light and can easily penetrate people's clothing; compared with X-rays, they are safe and will not It destroys biological tissues and is suitable for use in security and medical imaging. It is also materially distinguishable and can be used to identify contraband such as drugs and explosives."
Therefore, terahertz waves can be described as a natural "anti-terrorism and security "experts." Many explosives and their related components and drugs have fingerprints in the terahertz band, which can provide security warnings in densely populated areas such as airports, stations and terminals. Existing metal security doors and hand-held metal detectors do not recognize non-metallic materials such as ceramic tools, 3D printing guns, plastic explosives, etc., but these materials have a certain absorption in the terahertz band. Using passive terahertz imaging technology, the terahertz wave emitted by the human body is used to effectively identify the contraband hidden under the clothes, and at the same time ensure that there is no radiation to the human body. Therefore, it is highly valued by countries in the field of security inspection and counter-terrorism. .
It can be detected through normal passage, and the intelligent terahertz robot security detector is more than 20 times more efficient than manual security.
“Simply speaking, the terahertz human body security device is a two-dimensional terahertz 'snapshot' that forms a human body by passively receiving the terahertz wave emitted by the human body. After the object is hidden in the clothing, the absorption is absorbed. And blocking some or all of the human body terahertz waves, so that the intensity of the corresponding position between the corresponding object in the 'snapshot' and the human body background, to detect the existence of the item, and display the shape of the item and its location on the display screen position."
