由于激光荧光传感器提供了自己的激发源，因此它们被称为主动传感器。作为主动传感器，激光荧光传感器可以在白天或完全黑暗中全天候使用。某些化合物，如芳香烃，存在于石油中，吸收紫外线激光，并成为电子激发。这种激发被荧光发射过程迅速消除，主要是在光谱的可见光区域。通过仔细选择激发激光波长和在选定的发射波长下的范围选通检测，可以检测石油并将其分为三大类：本文将综述激光荧光传感器在溢油应用中的发展，重点介绍激光荧光传感器的系统组成，如激发激光源，以及允许这些独特的传感器用于石油的检测和分类的检测方案。近年来已经开发了许多激光荧光传感器，其中许多是严格的研究和开发工具。这些荧光传感器中的某些是舰载仪器，安装在飞机上，用于偶尔的空中使命。其他系统永久安装在飞机上，用于监视或泄漏反应。(C)2003年由爱思唯尔有限公司出版
As laser fluorosensors provide their own source of excitation, they are known as active sensors. Being active sensors, laser fluorosensors can be employed around the clock, in daylight or in total darkness. Certain compounds, such as aromatic hydrocarbons, present in petroleum oils absorb ultraviolet laser light and become electronically excited. This excitation is quickly removed by the process of fluorescence emission, primarily in the visible region of the spectrum. By careful choice of the excitation laser wavelength and range-gated detection at selected emission wavelengths, petroleum oils can be detected and classified into three broad categories: light refined, crude or heavy refined.This paper will review the development of laser fluorosensors for oil spill application, with emphasis on system components such as excitation laser source, and detection schemes that allow these unique sensors to be employed for the detection and classification of petroleum oils. There have been a number of laser fluorosensors developed in recent years, many of which are strictly research and development tools. Certain of these fluorosensors have been ship-borne instruments that have been mounted in aircraft for the occasional airborne mission. Other systems are mounted permanently on aircraft for use in either surveillance or spill response roles. (C) 2003 Published by Elsevier Ltd.
