Abstract: A laser is used in the detection of explosives residue by creating micro-detonations of explosive particles adhered to objects. An object is scanned with a beam of coherent laser light to induce micro-detonations of micro-particles of explosive residue adhered to the object. Temporal and spectral information representative of light emitted by the micro-particles is used to characterize the explosives.
