Hyperspectral detection of petroleum impurities in soil
Project ID : 6-2012-386
Technology
A spectrometer is used in the field to measure reflected radiation from soil samples over a wide frequency range. The resulting spectrum intensity data is analyzed and compared to a stored database and the presence of hydrocarbons in the soil is detected.
Background and Advantages
Reflectance spectrometry uses the reflective part of the electromagnetic radiation across the VIS-NIR-SWIR spectral region (350-2500nm) that illuminates the target in question and collects the reflected radiation from its surroundings. The ratio between the incident and reflected radiations across the entire spectral bands (a spectrum) holds significant chemical and physical information about the sensed target. For diagnosing areas suspected as contaminated and the possibility to control the rehabilitation process, there is a great need for an objective environmentally friendly method to rapidly detect low concentrations of petroleum hydrocarbon in soils. Current methods are based on chemical analysis and require acquiring samples, transportation to a laboratory and labor intensive analysis with expensive equipment. Our technology allows rapid in-situ measurments with standard spectrometers.
