With the integration of the laser scanner in the security inspection system, it will be possible to upload a variety of products purchased in duty free shops - even if they are over 100 milliliters. The laser scanner will also quickly detect and identify traces of various drugs and suspicious powders
The Israeli electro-optics company Laser Detect Systems (2010) Ltd, which develops and manufactures systems for detecting materials using lasers, reveals the development of a new laser scanner that will be used for aviation security and border crossing control. The LDS 5500 D model scanner will allow the loading of drink bottles, alcohol and various cream containers into the passenger compartment even if they are over 100 milliliters in volume. The system will alert within a few seconds of the presence of standard and improvised explosives even if they have been mixed with other materials in order to make detections more difficult. The laser scanner will also warn of the presence of dangerous powders and various drug residues.
The scanner has the highest detection speed, sensitivity and reliability available in the market of systems for detecting liquid explosives in aviation security. In a quick scanning process of only three to five seconds, an indication is received on the system monitor whether the tested products are allowed to board the plane or not. In case of suspicion of finding explosive substance remains or drug remains, the system displays on a color touch monitor, a red warning indicator alerting to the discovery of dangerous substance and the scanning chamber is automatically locked. In addition, as needed, a graphic display is shown that includes a chemical analysis, indicating the list of the components of the substances found to be suspicious.
Security officials are showing great interest in the new Israeli development and the system will soon be revealed to the general public and will be shown in action for the first time to terrorism experts and users from all over the world as part of the Counter Terror Expo 2012 international conference and exhibition to be held between the 25th and 26th of April in London.
The system was developed during the last two years at the expense and with the assistance of the security services in Israel and in accordance with the operating concept and Israeli security requirements. The system has successfully passed a series of tests and experiments carried out by external expert laboratories against a wide variety of explosives, some of which are unique explosives that have not yet been detected by means and other testing technologies. The company is currently working to obtain approvals in accordance with European and American standards.
President of LDS company Eli Venetia: "We are proud to reveal Israeli technology that will be used by international aviation security. To the best of our knowledge, this is one of the best performing inspection systems on the market today. The application of the Israeli operating concept in combination with the technology we have developed to detect and identify a wide variety of explosives at record speed, and with high reliability, will undoubtedly allow us to be a major player in the field and among the leading companies in the entire world in the field of testing technologies"
Since the attempted terrorist attack in London in August 2006, in which an Islamic terrorist squad tried to blow up a plane while it was in the air using liquid explosives that were brought into the passenger cabin, a regulation has been implemented in most airports in the world, especially in Europe and the USA, which does not allow passengers to carry in their hand luggage packages containing liquids or creams in the amount of Over 100 milliliters per case.
For years now, the ban has caused huge losses to Duty Free stores, especially on transit flights, and the anger of many passengers who have to stand in long check-in lines and "say goodbye" to the drinking bottles, alcohol bottles and valuable perfumes purchased at the airport and thrown in the trash, in extreme cases even parents who were not allowed to bring bottles of milk onto the flight for babies
Some European countries have already announced recently that starting in April 2013 they intend to cancel the installation and at the same time they intend to equip themselves with large quantities of electronic inspection systems that will allow drinking bottles and other liquids to be brought into the passenger cabin and the belly of the plane safely.
"Beyond the security interest, as mentioned, there is a distinct commercial interest of the duty free stores, which lose sales of millions of dollars every day. The scope of the global market for high-quality scanning systems with an emphasis on aviation security and border crossings has a huge potential of many hundreds of millions of dollars and we hope to be a significant part of this market" added company president Eli Venezia
The Israeli company's developments are protected by patents and are based on a technology that includes several methods and analyzes for analyzing the spectrum of the returning light of a laser beam called: Laser Gated Raman Spectroscopy A laser beam of different wavelengths scans the product being tested, the molecules or crystals that the beam hits react to the laser beam, emitting and scattering light in a way different and in wavelengths that are unique specifically to the components of the scanned material and thus constitute its 'identity card'. Light waves emitted from the tested material or its remains on the cases are optically collected and concentrated by an optical fiber into a sensitive light spectrum detector and decoded by the system computer using various methods and algorithms for analyzing the repeating laser spectrum and filtering the background "noise". Using these unique decoding methods, it is possible to accurately diagnose the type of explosive or drug, even if, as mentioned, it is mixed with various other substances in order to mask it.
At the Counter Terror Expo 2012 conference and exhibition, the Israeli company LDS will also present the development of a new generation laser system for the remote detection of side charges, explosives and various IEDs using laser spectroscopy. The MAGSHOE system of the Israeli company IDO SECURITY, based on magnetometer technologies, will also be presented at the company's booth, allowing for the rapid detection of suspicious metal objects up to 18 inches from the ground. The MAGSHOE system is already in regular operational use in Israel, and at other airports around the world.

1. Semi-transparent still allows discovery.
2. Indeed it is now about a single bottle at a time.
3. Molecules are indeed detected, but not those that have evaporated.
4. There is penetration into the transparent or semi-transparent container/bottle.
5. Semi-transparent plastic bottles also allow inspection.
Yair, you have a mind, the answer is within the question
A system claims to identify remnants of materials leaking from the tank. Do not penetrate into the container.
Yair, I understand that only molecules that have evaporated are detected even if their concentration in the air surrounding the object is very low.
I didn't notice the picture, probably Michal Michal.... I would still appreciate an answer regarding the first question, how is a laser beam that is a beam of light able to test containers that are not transparent?
I did not understand, if the tube or container containing the substance is not transparent but made of an opaque material (metal or plastic) how is the laser beam able to penetrate?
Also, is it necessary to check each container separately? Or does the system scan the entire contents of the suitcase without opening it as is customary today with the mirroring machines?
