Raman spots traces of buried landmines

Tests at Robert Gordon University confirm ways to remotely identify explosives in soil environments.

Buried landmines represent a major threat to life and an impediment to relief efforts in several parts of the world, so landmine detection technology is in high demand.
Advances in the design and utility of unmanned aerial drones have been an asset in landmine location, potentially allowing suitable optical sensing technology to be mounted on a drone and survey the territory of interest from the air, without direct human involvement.

In a presentation to SPIE Security+Defense, Shruti Karnik of Aberdeen’s Robert Gordon University (RGU) described the latest trials using Raman spectroscopy as a nondestructive, remote sensing and potentially drone-borne technique able to detect traces of explosives characteristic of hidden landmines.
