Abstract

In this work we examine the feasibility of active thermal sensing of buried objects. A 1.5 kW carbon dioxide laser is used to provide a thermal impulse to the surface of a sand test bed containing simulated metallic landmines. Time- dependent thermal images of the induced surface temperature differentials are obtained using an infrared focal plane array imaging system. Experimental results are reported for two target sizes and four thermal pulse conditions. Quantitative evaluation of the induced surface temperature differentials as a function of time are presented.
