safely. The detection of crude oil in the sand near the sea is of significance to petroleum exploration and environmental
protection. Reflected terahertz time-domain spectroscopy is used for the quantitative detection of the crude
oil in the sand. A detailed analysis is performed about the delay time and wave velocity across the sample. The research
indicates that the relationship between the crude oil concentration and the delay time shows linear decrement
character,the reflected terahertz time-domain spectroscopy is a potential method for quantitative detection in the
environmental protection.
Key words: crude oil; terahertz wave; pollution; quantitative analysis
