Ying Wang (Ph.D. ’12), working in conjunction with her advisor, associate professor Yu Lei, has developed a prototype portable sensing system that can be used to detect hidden explosives like landmines accurately, efficiently, and at little cost.
The key to the sensing system is an advanced chemically-treated film that, when applied to the ground and viewed under ultraviolet light, can detect even the slightest traces of explosive chemical vapor. If there is no explosive, the film retains a bright fluorescent color. If a landmine or other explosive device is present, a dark circle identifying the threat forms within minutes.
