Stand-off hyperspectral imaging with a turn-key Mid-IR QCL dual-comb spectrometer for trace explosives detection

Not Accessible

Your library or personal account may give you access

Abstract

The identification of explosives residue and other harmful materials in field is a key problem to solve for world safety. Here we present a point-by-point imaging technique based on stand-off dual-comb spectroscopy carried out with QCL frequency combs using a fast scanning technique to provide hyperspectral images with species specific absorption spectra.
