Abstract
The method of determining the presence of a spill of a petroleum product by the detection of a petroleum-derived volatile organic compound (VOC) generally has a step of providing an ultraviolet (UV) radiation generator and a receiver assembly aimed at a scene; a step of illuminating a distant target in the scene with a UV radiation beam, the UV radiation beam having an excitation wavelength being tuned to a resonance Raman excitation wavelength of the petroleum derived VOC; a step of receiving a return signal from the distant target; and a step of determining the presence of the petroleum-derived VOC upon detecting Raman scattering in the received return signal, the Raman scattering being indicative of a resonance Raman interaction between the UV radiation beam and molecules of the petroleum-derived VOC.
