Patented research remotely detects nitrogen-rich explosives
Date:4/17/2014

s a material might contain nitrogen-rich explosives.

"The work focuses on quickly detecting improvised explosive devices as far away as possible," Dunn said.

Currently, the unmanned system can work for distances around 1 to 3 meters away, but the researchers would like to make the system effective at 100-meter distances, which is nearly the length of a football field, Dunn said.

The patented technique and templates could be modified to detect other substances, Dunn said. For instance, police can use the template technique to detect drugs through airport security or other points of border entry.

Dunn's research team continues to improve the detection technology. They are developing ways to more quickly detect explosives in different positions and different sizes.

"We are looking at what is the minimum number of templates we can have in our library that would differentiate the largest number of IEDs from inert targets," Dunn said.

The researchers are improving other measurements that are not directly related to radiation but affect the detection of explosives. For instance, humidity affects radiation's ability to infiltrate the air. If researchers can adjust the method based on a site's humidity conditions, they can improve the detection system's accuracy.
