My Note: My read of the news today about the new Chinese scanner is that it appears to use passive THz scanning technology. I base this on the following quote in the news release:
Terahertz radiation is a kind of electromagnetic radiation with wavelengths between those of infrared rays and microwaves, boasting a strong penetration force without harmful effects.
The human body naturally transmits terahertz waves, which can be received by the terahertz body scanner.
By contrasting the image projected on the scanner screen with the background image of the human body, security staff can determine if a person is hiding something in their clothes as the object would deflect or hinder the terahertz transmission path.
If in fact, this is the case, then it would be interesting to know how it differs from the product line offered by Digital Barriers, (which obtained this technology from ThruVision), and which is supplying the new stand-off THz detection system to the NYPD.
I had some readers wonder if this new Chinese product was the result of reverse engineering of the API T-5000 and perhaps this product will in fact incorporate pulsed scanning using, as well as passive scanning. As always I am writing various individual who may know more, and will share what I find out.
Advanced Photonix® (NYSE MKT: API), the leading supplier of terahertz systems to industry, announced today that it has sold a T-Gauge® terahertz sensor to Shanghai Gaojing in Shanghai, China. The system, equipped with a high-speed line scanner, will be integrated into a new security platform being developed as part of a major national program for security instrumentation.
Shanghai Gaojing Radiography Technology Co., a major supplier of baggage inspection systems, has purchased the latest in industrial terahertz systems, the T-Gauge® terahertz sensor from API. Terahertz has shown significant capability in detecting explosives, drugs, and other threats in packages or checked bags. The T-Gauge® sensor was chosen because of its robust performance, its high-speed data acquisition, and its ease of integration.
