Underwater Oil Spill Imaging via UV LED-induced Fluorescence

Abstract

In this research, we describe the concept of underwater oil spill imaging technology based on the UV-induced fluorescence. This imaging system is composed of the ultraviolet LED (Light Emitting Diode) lights and the CCD (Charge-Coupled Device) image sensor. For the identification of the proposed imaging system, we conducted the lab-scale validation tests to classify the difference between the oil samples and the background. For the comparison between oil samples and seawater, we analyzed the images acquired from tests which were performed in different conditions. Through these tests, we can visualize the shape of underwater oil and also distinguish the oil samples from seawater. From this experiment using the proposed setup, we can confirm the possibility of this system for the underwater oil spill imaging system by UV LED-induced fluorescence.ce) image sensor.
