3D millimeter wave body security door
3D millimeter wave human security door is an advanced security equipment, the following is a detailed introduction of 3D millimeter wave human security door:
一、Definition
3D millimeter wave human security door is the use of millimeter wave technology for human security equipment, which can generate three-dimensional holographic images of the detected person, so as to achieve a comprehensive, rapid and accurate scanning and detection of the human body and carry-on items.
二、Working principle
The working principle of the 3D millimeter wave human security door is based on the characteristics of millimeter waves. Millimeter wave refers to electromagnetic waves with frequencies between 30GHz and 300GHz and wavelengths between 1 mm and 10 mm. The millimeter-wave security gate transmits millimeter-wave to the detected personnel through the antenna. After the millimeter-wave encounters the human surface and the area covered by clothing, part of the energy will be reflected back and received by the antenna of the security gate. Due to the different absorption and scattering characteristics of millimeter waves on the surface of the human body and the area covered by clothing, the strength of the reflected signal will also be different. The receiver in the security gate will process the received reflected signal, and through computer image processing technology and algorithms, the reflected millimeter wave signal will be converted into an image, showing the outline and shape of the surface of the human body and the clothing covered area, so as to achieve the detection of dangerous goods.
三、Feature
Non-contact detection: The 3D millimeter wave human security door can be detected without touching the person being tested, avoiding the discomfort and aggression that may be caused by traditional security screening methods.
High penetration: millimeter waves can penetrate clothing and other occlusions to detect dangerous items hidden under clothing, such as guns, knives, explosives, etc.
High precision: Through advanced image processing technology and algorithms, the 3D millimeter wave human security door can accurately identify the dangerous goods carried by the detected person, and clearly indicate the specific location of the target object.
High efficiency: The detection process is fast, and a large number of personnel can be checked in a short time, improving the efficiency of security check. At the same time, it can also scan from different angles, and the detection is more comprehensive.
Low radiation: millimeter wave is an electromagnetic wave that does not cause harm to the human body, and the scanning speed is fast, and the impact on the human body is almost negligible.
Privacy protection: Because the 3D millimeter wave human security door has high resolution and good privacy protection characteristics, it can display dangerous goods at the same time, without too much exposure to personal body details, which is especially important for the protection of privacy.
四、Application
Because of its efficient, accurate and safe characteristics, 3D millimeter wave human security gates are widely used in airports, high-speed railways, subways, large venues, prisons, customs and border, military bases, key government departments and other places that require strict security checks.
In summary, 3D millimeter wave human security door is an advanced security equipment, with non-contact detection, high penetration, high precision, high efficiency, low radiation and privacy protection characteristics, is widely used in a variety of places requiring strict security.
