Additionally, a system also including a Raman scattering controlled substance detector is disclosed.
Claim 1
A system for detecting controlled substances on an object comprising: at least one laser for illuminating at least part of an object with laser energy at a firstwavelength; a second harmonic detector for detecting laser energy scattered from said object to detect scattered laser energy having a second wavelength which is a second harmonic of said first wavelength, wherein detection of scattered laser energyhaving a second wavelength which is a second harmonic of said first wavelength indicates that one or more controlled substances may be present on said object; and at least one additional controlled substance detector comprising at least one of atime-resolved luminescence controlled substance detector for detecting luminescence produced by impingement of said laser energy, wherein detection of luminescence indicates that one or more controlled substances may be present on said object, and aRaman scattering controlled substance detector, for detecting Raman scattering produced by impingement of said laser energy.
