Hyperspectral Imagery for Large Area Survey of Organophosphate Pesticides.

摘要

Current detection of organophosphate pesticides in residential settings involves taking swipe samples at locations of potential contamination and conducting lab analysis. This method provides results that are applicable only to the points where samples were taken. A standoff detection method utilizing hyperspectral imaging would allow for analysis of a larger area without the need for lab analysis. This report demonstrates a proof of concept experiment that shows the applicability of hyperspectral imaging for the detection of organophosphates. The differences in detection on reflective and non-reflective surfaces are also explored. To the author s knowledge, this research is the first to use the Telops longwave infrared hyperspectral imager to positively identify and locate dimethyl methylphosphonate on both reflective and non-reflective surfaces.
