Laser That Can “Listen” and Detect Bombs

September 20, 2011 Leave a comment Go to comments

“A research team at Michigan State University has developed a laser that could detect roadside bombs – the deadliest enemy weapon encountered in Iraq and Afghanistan.

The laser, which has comparable output to a simple presentation pointer, potentially has the sensitivity and selectivity to canvas large areas and detect improvised explosive devices – weapons that account for around 60 percent of coalition soldiers’ deaths.

Marcos Dantus, chemistry professor and founder of BioPhotonic Solutions, led the team and has published the results in the current issue of Applied Physics Letters…

The laser beam combines short pulses that kick the molecules and make them vibrate, as well as long pulses that are used to “listen” and identify the different “chords”.

The chords include different vibrational frequencies that uniquely identify every molecule, much like a fingerprint. The high-sensitivity laser can work in tandem with cameras and allows users to scan questionable areas from a safe distance.”
