• AIRPORT SECURITYReimagining Imaging at the Airport

    The Science and Technology Directorate (S&T) and Transportation Security Administration (TSA) are collaborating on Advanced Imaging Technology to improve the passenger screening experience.

  • EXPLOSIVES DETECTIONSniff Test for Explosives Detection Extends Its Reach

    By Tom Rickey

    Scientists have developed a way to detect tiny amounts of hard-to-detect explosives more than eight feet away, reducing the need to swipe clothing, luggage or other materials. The nNew method detects dangerous materials with lower vapor pressure.

  • AIRPORT SECURITYPrototype Self-Service Screening System Unveiled

    TSA and DHS S&T unveiled a prototype checkpoint technology, the self-service screening system, at Harry Reid International Airport (LAS) in Las Vegas, NV. The aim is to provide a near self-sufficient passenger screening process while enabling passengers to directly receive on-person alarm information and allow for the passenger self-resolution of those alarms.

  • SECURITY SCREENINGSpeedier Security Screening in the Palm of the Hand

    Though pat downs are currently an essential element of keeping travelers safe at the airport, it slows the screening process for people waiting in line and can be an uncomfortable experience for the passenger being screened. Reducing the need for pat downs may soon be easier.

  • DETECTIONLeveraging Artificial Intelligence in Explosives, Narcotic Detection

    DHS S&T is applying emerging technologies in the development of artificial intelligence / machine learning technologies – and searching for ways to use these technologies to identify dangerous compounds, like those found in explosives and narcotics.

  • AIRPORT SCREENINGA Self-Service Screening Option Coming to the Airport Near You

    Self-service screening is coming to airport checkpoints, thanks to the Science and Technology Directorate’s Screening at Speed Program. A pilot of a new self-service screening system is scheduled to begin in January at Harry Reid International Airport in Las Vegas, Nevada.

  • EXPLOSIVES THREATBetter Resources to Mitigate Explosive Threats

    Every second counts when responders encounter an explosive device, and critical decisions must be made quickly in order to neutralize the threat while also ensuring the security of civilians, property, and the responders themselves.

  • AIRPORT SECURITYImproving the Speed and Safety of Airport Security Screening

    By Anne McGovern

    For decades, airports around the nation have employed sensitive canine noses to detect concealed explosives. While this four-legged fleet has been effective and efficient, researchers have yet to build a mechanical method that can mimic their abilities. Researchers seek ways to build non-contact screening methods that can detect concealed explosives at airports.

  • EXPLOSIVE DETECTIONThe Next Generation of Explosives Trace Detection is Here

    Launched in fiscal year 2020, NextGen Explosives Trace Detection (ETD) expands the scope of aviation checkpoints technology, resulting in the advancement of technologies that can quickly and accurately collect and analyze samples in a variety of ways, including from direct contact with the subject, non-contact sampling via vapors, and even through barriers.

  • EOD/IED & COUNTERMINE INITIATIVESIdentifying and Neutralizing New Explosive Threats

    The IED threats from insurgent characterized the wars in Afghanistan and Iraq, but now the U.S. military is focusing on neutralizing bombs and mines that it could face in future conflicts against more advanced adversaries. DSI October 2022 EOD/IED & Countermine Symposium will highlight current initiatives toward identifying and neutralizing explosive threats to the homeland and critical infrastructure.

  • DETECTIONDeep Learning Technology for Faster and More Accurate Terahertz Security Inspection

    With the strengthening of global anti-terrorist measures, it is increasingly important to conduct security checks in public places to detect concealed objects carried by the human body. A new detection method can be used for accurate and real-time detection of hidden objects in terahertz images. 

  • AIRPORT SECURITYRemote Screening Demonstration at Cape Cod Gateway Airport

    DHS S&T successfully conducted a demonstration of remote screening infrastructure for airport security checkpoints. The Integrated Defense & Security Solutions (IDSS) can send computed tomography (CT) X-ray images of carry-on baggage flagged for threats to remote locations for near real-time analysis.

  • EXPLOSIVES DETECTION3D X-Ray Makes it Easier to Detect Hidden Explosive Weapons

    As travelers pass through border crossings, ports of call, airport checkpoints, and various precautionary measures in both federal and private venues, their safety and wellbeing are constantly ensured through various forms of screening technologies that have one critical goal: to identify and alert the proper authorities to potential threats. These technologies do their jobs very effectively, but it is important to ask the question: Can they be improved?

  • AIRPOR SECURITYComputer Code to Speed Up Airport Security

    Imagine moving through airport security without having to take off your shoes or belt or getting pulled aside. Researchers are working on the Open Threat Assessment Platform, which allows the Transportation Security Administration to respond more quickly and easily to threats to air travel safety.

  • BOMB SQUADSDIY Innovations for Bomb Squads

    Bomb-squad members must effectively employ critical thinking and problem-solving skills while working in stressful, potentially life-threatening situations. DHS S&T notes that bomb technicians’ ability to expect the unexpected and adjust accordingly has created a consistent pipeline of do-it-yourself (DIY) inventions to solve everyday issues they face, and the S&T works to validate these innovations.
