Abstract We demonstrate the remote detection method of oils in water by laser Raman spectroscopy. A frequency-doubled, Q-switched Nd:YAG laser at 532 nm was used as a light source, and oils in water were identified in the optical cells placed 2 and 4 m away in a water tank by using the Raman signals at 2910 cm−1 from oils. The results show that the configuration of underwater remote Raman spectroscopy can be a useful alternative method for detecting oil leaks from subsea pipelines, potentially providing more capability of target selectivity as compared with fluorescence detection

使用激光拉曼光谱远程检测水中的油

摘要 我们展示了激光拉曼光谱远程检测水中油类的方法。使用532 nm的倍频调Q Nd:YAG激光器作为光源，利用2910 cm的拉曼信号在距离水箱2和4 m处的光池中识别水中的油-1 来自油。结果表明，水下远程拉曼光谱的配置可以成为检测海底管道漏油的有用替代方法，与荧光检测相比，有可能提供更多的目标选择性能力
