Airports Trial Scanners That Could Put an End to Liquid Restrictions
Jackie Reddy November 06, 2014
New technology capable of “reading” chemical signatures could render current liquid allowance a thing of the past.
Carry-on liquid restrictions could soon be obsolete thanks to the Insight100, a scanner developed by U.K.-based Cobalt Light Systems. The scanner uses laser technology to determine the chemical composition of liquids in containers without opening them. Currently on trial at London Heathrow Airport (LHR), Gatwick Airport (LGW), as well as 63 other airports across Europe and Australia, the developers hope that the Insight100 will allow passengers to carry standard-sized cosmetics, drinks and toiletries.
Firing a laser into liquid at different angles, the Insight100 analyzes scattered light and recognizes the unique patterns created by different materials. This light penetrates the liquid’s surface and is “read” by the scanner, which subtracts data about the container from the reading and reveals the liquid’s chemical signature. The chemical signature is then checked against a catalog of dangerous materials. The screening process takes only a few seconds, and it’s believed that this technology could significantly reduce the time it takes to get through security checkpoints.
Since 2006, travelers have been limited to a maximum carry-on liquid allowance of 3.4 fluid ounces per container, with all containers required to be placed in clear bags for inspection. The European Commission aims to lift the restriction by 2016.
The Insight100 can scan containers of up to 3 liters in size, while sister model — the Insight100M — allows agents to screen metallic containers. With an error rate of less than 1 percent, Cobalt Light System’s CEO Paul Loeffen believes these scanners will reduce the frustration and costs associated with the current restrictions. He described the technology to MailOnline Travel as “part of the solution towards the legislation that is aiming to lift the restrictions on carrying liquids into cabin baggage over the next few years.”

Ending the liquids ban would also solve the "problem."
.... Yeah these have been in Japan for quite a long time now, not sure why these are touted as "new."
Himeno is correct--the liquid scanners in Japan are just one reason why domestic travel in that country is more pleasant. I hope they roll these out soon.
There are liquid scanners in the U.S. already which are used for medicines and other necessary liquids. Don't expect these to make a difference in what is allowed on board. Can you imagine the delay individually scanning several different bottles for EACH passenger? Ain't gonna happen.
They've had liquid scanners in Japan for years. Not that they are needed. The entire liquid limits is completely unjustified.
