Background technique
With the lasting wildness of the upheaval and terrorist activity increasingly of international situation, traditional safety inspection means are gradually
It is unable to satisfy demand, especially in human body safety check field.The mode that metal detector cooperation is searched manually is current using more
Extensive human body safety check means, but often rate of false alarm is high for this mode, inefficiency, and is easy to be discovered and advised by a bad actor
It keeps away.THz wave is electromagnetic wave of the frequency in 0.1~10THz (30 μm~3mm of wavelength).Milli of the THz wave with its frequency spectrum two sides
Metric wave as infrared ray, detection and in terms of can excavate out completely new technology, thus realization examined in safety check, medical treatment
The all more important applications in fields such as disconnected, non-destructive testing, inspection and quarantine.Especially in terms of human body safety check, the photon of THz wave
Energy will not cause ionising radiation to injure human body well below X-ray, and its wavelength is more shorter than millimeter wave, thus
The imaging effect of higher resolution can be obtained.THz imaging technology has become human body peace most promising at present
One of procuratorial organ's case, the extensive concern by lot of domestic and foreign R&D institution and safety check manufacturer.
The mode that existing Terahertz rays safety detection apparatus usually relies on mechanical scanning obtains the human body image output of a whole picture, such as
Patent CN204882899 describes a kind of light channel structure of human body safety check instrument, and core is a drum-type multi-panel reflecting rotating mirror,
Numerous electronic, mechanical, optical elements are cooperated to be scanned imaging to human body.Patent CN105044017A describes another fixation
