Terahertz wave is actually a wavelength between infrared and microwave electromagnetic waves, it has a strong penetration, can easily penetrate clothing, the human body itself will produce this electromagnetic wave and radiation outwards, when people wear clothing hidden items, because the object of the terahertz wave to varying degrees of absorption and blocking, Makes a comparison of the intensity between the position of the corresponding item in the two-dimensional strength map and the human background, so as to detect the existence of the item and display the shape of the item and its location on the display.
Passive terahertz human imaging technology, can achieve the human carry-on items of visual, non-contact, radiation-free safety inspection. In the future can be widely used in airports, railway stations, subways and other security checks, public security checkpoints, courts, letters and visits, prisons, border control, customs and sports stadiums, exhibitions and other security.
At present,Our country'sPersonal security checks mainly take the walk-through metal detection door, supplemented by portable hand-held metal detector close scanning and security personnel manual "shoot, touch, press, press" the form of suspicious items. In this mode, the metal detection device only gives tips to the metal material, and forBy security personnelNon-metallic contraband (e.g. explosives, powders, liquids, plastics, ceramics, glass, etc.) that carries with you cannot be effectively detected, and the means of detecting the door through the metal are single,The person being examinedThe precision of the positioning of the metal items carried is limited and cannot provide visual images as the basis for the determination.
At the same time, the limitations of metal detection equipment, so that the personal security process also needs security personnel through manual "shoot, touch, press, press" the form of suspicious things. To ensure the quality of security, the rapid checker speed of the combination of security hand inspectors needs at least 15 seconds/person, a hand inspector can only check 240 people an hour, withCrowdedPeak-hour intake is clearly out of proportion。And，This close-up touch security brings a very poor customer experience, and seriously affects the real-time pass rate, easily triggering passenger dissatisfaction, and even lead to denial of check-in disputes, physical conflict. In respect for passenger privacy, avoid causing disputes and effective detection of dangerous goods work task between the contradictions, so that many security personnel in the process of personal inspection there is a fear of difficulties, hand inspection process perfunctory.
Security is important, but the process is cumbersome and time-consuming, and has been bothering passengers and staff.ThruVision Wall HangingTaihertz body security system, simple and fast,No need to stay, God unknowingly.You can easily complete the security process, in the premise of ensuring the safety of personnel also improve the efficiency of security.
ThruVisionWall-mountedTerahertz human securitySystem , the use of passive imaging principle, safe and non-radiation, can not infringe the privacy of the person being examined in the case of unknowingly completed security checks.
1）Passive, non-intrusive (non-invasive):No ionizing radiation, safe use by the general public, no problems associated with pregnancy or pacemakers. No invasion of privacy, can be used in public places, no need for the same gender to operate.

(iv)ThruVision - Cracking human security challenges, efficient, safe and reliable solutions
1, human security can avoid health and ethical risks?
2, the existing human security camera can take into account security and efficiency?
ThruVision passive terahertz human imaging security system unique contactless body screening method, better to solve the above problems, its compact size and mobility, making fixed and mobile become the ideal security checkpoint.
Improving security efficiency: God don't know, ghost snobbes over security；
Easy and fast operation: fixed, mobile, covert combination, can be managed remotely;
Contactless inspection: 3-15 m long-range imaging;
Make up for the traditional security check: can be combined with the regular security system, do not change the original security program and the scene.
