Fiber Optic Infrared Cone Penetrometer: Results of the May 1995 Field Test

摘要

A fiber optic system for remote, in-situ detection of hydrocarbon contaminationin soils was developed for use with the cone penetrometer. The system uses infrared transmitting chalcogenide fibers to measure the infrared spectrum of light diffusely reflected from the soil undergound to identify and quantify organic contiminants such a fuels, oils, chlorinated compounds, and BTEX compounds (benzene, toluene, ethylberizene, and xylene). A field test of the prototype system was conducted at Dover AFB in May 1995. The results of the test are summarized in this report.
