- Standoff scanning dual-comb spectroscopy of explosive materials is demonstrated with quantum cascade lasers at <inline-formula> <tex-math notation="LaTeX">\sim 8~\mu \text{m} </tex-math></inline-formula>. The proof-of-concept of the spectrometer, capable of the detection and identification of explosive materials at a distance of 3 m, has a detection limit of cyclotrimethylenetrinitramine (RDX) and pentaerythritol tetranitrate (PETN) on various surfaces of 5-<inline-formula> <tex-math notation="LaTeX">8~\mu \text{g} </tex-math></inline-formula>/cm 2 in a scanning regime and 2-<inline-formula> <tex-math notation="LaTeX">3~\mu \text{g} </tex-math></inline-formula>/cm 2 with stationary beam in reflection-absorption and backscattering modes.
