Terahertz waves are between microwaves and infrared, with a frequency range of 0.1~10 THz and a wavelength of 3mm~30μm.

Terahertz waves, like millimeter waves and infrared waves on both sides of the spectrum, are capable of unearthing brand new technologies in detection and imaging, thus realizing many important applications in the fields of security screening, medical diagnosis, non-destructive testing, inspection and quarantine, and so on. Especially in human security, the photon energy of terahertz wave is much lower than X-ray, so it will not cause ionizing radiation damage to the human body, and its wavelength is shorter than millimeter wave, so that it can obtain a higher resolution of the imaging effect. Terahertz imaging technology has become one of the most promising people with the inspection program, by many domestic and foreign research units and security manufacturers of extensive attention.

Terahertz spectroscopy and imaging technology is an important content of terahertz science and technology, in physics, chemistry, biology, security, aerospace and other fields have important application prospects, is an emerging, efficient, multi-disciplinary intersection of coherent detection technology.

 With the development of society and the continuous progress of science and technology, law enforcement agencies are facing more and more difficult problems and adjustments, the work to be carried out in the security check occasions are no longer limited to the traditional subway, airports, railway stations and other fixed locations, venues, exhibition halls, assemblies occasions of the security needs are also growing, however, such occasions of security checks have a high degree of mobility and temporary, the installation of permanent security check equipment is completely unnecessary, but there is no Security equipment will bring great workload to the security personnel, therefore, the design of a flexible mobile location, and take into account the security function of the security equipment becomes very necessary. With the increasingly volatile international situation and the continued prevalence of terrorist activities, the traditional means of security checks have gradually been unable to meet the demand, especially in the field of human security checks, people with the same check. Metal detector with manual search mode is currently more widely used means of human security checks, but this mode is often a high false alarm rate, inefficient, and easy to be dangerous molecules to detect and avoid. Our portable terahertz security checker came into being.

Our company has relevant national patents in the field of terahertz security checker.
