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.

[ We claim:] [1.] An apparatus for laser detection of micro-particles of explosive residue on the surface of an object to be inspected, said apparatus comprising:(a) a laser for generating a beam of coherent light;(b) optical means for scanning an object to be inspected with said beam of coherent light to induce micro-detonations of said micro-particles of explosive residue;(c) a detector means for sensing temporal and spectral information of light emitted from the impingement of said beam of coherent light on said object to be inspected during said scan and generating a data acquisition signal therefrom;(d) data processing means for comparing said temporal and spectral information in said data acquisition signal with one or more empirically obtained patterns of temporal and spectral information derived from laser induced detonation of said microparticles of explosives;(e) means for generating an alarm signal in the event said temporal and spectral information in said data acquisition signal matches one of said empirically obtained patterns.
