摘　　要：鉴于近红外光谱分析技术在纯品油鉴别中的成功应用,结合当前光电检测技术发展情况,设计了一种基于近红外光谱分析技术对海面溢油进行实时监测的光电检测系统。该系统应用烃类物质对特征吸收波长的光吸收作用随浓度的变化而变化的基本原理设计了光电传感探头,并采用有效的数据采集系统,进一步提高了测试精度。文章介绍了传感系统的工作原理设计,重点说明了光源的选择,并通过测试验证了系统的可靠性。In view of the near infrared spectroscopy successfully applied to pure oil identification and development trend of photodetection,a real-time monitoring of selectro-optical detection system was designed which could monitor the oil spills based on the NIRS.Photoelectric sensor probe was designed according to the basic principle of characteristic absorption wavelength of the light intensity changing with the concentration of spill,and used of effective data collection system to further improve the accuracy of the test.The working principle of the sensor system design,the choice of light source,and verified by testing the reliability of the system were described.
