Dual-band infrared imaging applications: locating buried minefields, mapping sea ice and inspecting aging aircraft
We discuss the use of dual-band infrared (DBIR) imaging for three quantitative NDE applications: locating buried surrogate mines, mapping sea ice thicknesses and inspecting subsurface flaws in aging aircraft parts. Our system of DBIR imaging offers a unique combination of thermal resolution, detecta...
