A kit designed to detect explosives uses pulsed focused energy to generate an acoustic wave, which gets picked up by a detector if explosives are present.

The detection of explosives is a critical matter for the safety and security of public places, military sites, airports, and many other locations. Traditional methodologies have employed techniques such as physical search, the use of sniffer dogs, or electronic machines to detect explosives. However, these traditional methods often expose the individual conducting the search or the machine scanning the scene to a potential explosion event. The principal problem with these approaches is the risk posed to human life and property in the event of an unexpected detonation. An additional challenge is the ability to detect explosives reliably without false positives, which can disrupt daily operations in public spaces. Moreover, these methodologies often do not offer remote detection capabilities. Hence, there is a clear necessity for a safer, more effective alternative to these conventional means.

Technology Description

The kit for detecting explosives includes a pulsed focused energy source located away from a targeted surface or substrate. This energy source has a magnitude potent enough to release the internal energy of any explosive substance if present on the substrate. The release of this internal energy consequently generates an acoustic wave. Furthermore, the kit includes a detector designed to identify these acoustic waves at a certain detection distance away from the substrate. One factor that differentiates this technology is its reliance on the generation and detection of acoustic waves for the identification of explosives. The method of employing a pulsed focused energy source is innovative, and its success in triggering an explosion does not rely on the physical interaction between the energy source and the explosive material. Instead, this technology uses the correlation between the energy released from explosives and the subsequent acoustic wave to identify the presence of explosives.
