Thanks to the new COMET technology, liquids can be identified exactly by their x-ray "fingerprint" and clearly distinguished from dangerous goods.

The inspection of hand luggage (carry-on) at airports has become a fact of life. Although it is inconvenient for passengers and also sometimes takes a personal toll when useful or valued items are forgotten in carry-on bags, such as a drink or a bottle of costly perfume above the size limit: Overall the process is tolerated by travelers in the knowledge that their own safety is paramount. It is very clear that around the world, geopolitical tensions, crises and acts of aggression have greatly heightened the urgency of this universal human need for safety and security. In many countries, security checks at the entrances to train stations, shopping centers, museums, tourist attractions and at major events are the new normal, and they remain a growing trend.

New x-ray modules will streamline security checks

To assure safe travel without extensive restrictions and lengthy waits, new solutions are needed. Such new systems must enable the swift, accurate and straightforward inspection of luggage. Some years ago the security industry therefore launched projects to develop and implement new inspection concepts. COMET is very involved in these initiatives.

In close cooperation with well-known partners worldwide, COMET is working to fundamentally optimize hand luggage inspection and thus develop a new application for its innovative, high-performance x-ray modules.

One of the key challenges is the definitive identification of liquids in bags, backpacks and suitcases. Currently all liquids – from water, to cologne, to baby food – must be removed from the luggage and inspected separately. Moreover, the examination of liquids takes time, even when the quantities permitted are as small as they are today.

One of the latest co-developments by COMET with a market leader in the security industry is based on x-ray diffraction. This approach uses radiographic “fingerprinting” of liquids to identify them conclusively and exactly. With this new technology, it will soon become possible to rapidly and precisely determine whether that bottle contains a soft drink or a dangerous substance. The solution from COMET thus brings greater security, but also more convenience, as the time-consuming emptying of luggage can be largely avoided.

The new technology will be tested by the customer in 2017 and may soon help enhance security in high-traffic locations through fast, straightforward and accurate inspection.
