Researchers at Michigan State University have developed a laser that would be used to detect roadside bombs, additionally referred to as improvised explosive devices (IEDs).
The device isn't any stronger than a typical presentation pointer, however it's the sensitivity and selectivity to scan giant areas and detect the chemicals utilized in these deadly bombs, that have accounted for concerning sixty % of soldier deaths in Iraq and Afghanistan.
The main challenge in identifying roadside bomb chemicals is that they're sometimes hidden among chemical compounds that mask the molecules that indicate the presence of a bomb.
"Having molecular structure sensitivity is important for identifying explosives and avoiding unnecessary evacuation of buildings and shutting roads because of false alarms," team leader Marcos Dantus, a chemistry professor at MSU and founding father of BioPhotonic Solutions, said in a very statement.
The laser developed by Dantus will distinguish explosives from non-harmful compounds for quantities as tiny as a fraction of a billionth of a gram, he said.
To do so, the laser beam sends out short pulses that kick the molecules and create them vibrate and long pulses to that researchers will "listen" and determine totally different "chords." These chords have totally different vibrational frequencies that may perceive every molecule, sort of a fingerprint. The laser can be used with a camera, thus troopers might scan a locality from afar.
"The laser and also the methodology we've developed were originally meant for microscopes, however we tend to were able to adapt and broaden its use to demonstrate its effectiveness for standoff detection of explosives," Dantus said.
The team's analysis was revealed within the current problems with Applied Physics Letters. it had been funded by a partial grant from the Department of Homeland Security, however Dantus said he hopes to amass further funding to assist take the technology from the lab into the sector.
