  • Patent number: 7829345
    Abstract: A method for detection of a peroxide-based compound includes directing ultraviolet light from an ultraviolet light source toward a location remote from the ultraviolet light source, where the ultraviolet light induces photodissociation of a peroxide-based compound located at the remote source into hydroxyl radicals and excitation of the hydroxyl radicals to fluoresce, capturing any fluorescence from the remote location that has been induced by the ultraviolet light directed from the ultraviolet light source toward the remote location, and analyzing the fluorescence that has been captured from the remote location to determine the presence of the peroxide-based compound at the remote location. A system for detection of a peroxide-based compound that performs such method steps is also described herein.

  • Patent number: 7760352
    Abstract: Systems and methods for performing Raman spectrometry wherein a Raman spectroscopy system is mounted on a vehicle for on the move contaminant analysis. The system is configured to interrogate a target with a laser at a predetermined pulse repetition frequency (PRF), wherein during each PRF cycle, defined as 1/PRF, the laser is dual pulsed at a first wavelength and at a second wavelength. Raman spectra are collected and used to identify the target by matching a Raman signature with a given collected Raman spectra.
