The US Transportation Security Administration (TSA) awarded a $6.8 million contract in 2013 to Edgewood, Maryland based Smiths Detection for new liquid-scanning systems that can detect hazardous liquids inside sealed bottles.
The new scanners, if successful, may possibly lead to an easing of restrictions on carrying more than 3.4 oz (100 ml) of liquids on flights.
The scanners, called RespondeR Bottled Liquid Scanners, use Raman spectroscopy technology to scan the bottles and display the results within 20 seconds.
The scanners can scan clear, translucent or frosted unopened glass or plastic bottles and display simple results such as “Potential Threat” or “No Threat.”
The TSA has not yet commented on the possible deployment of the scanners.
