Identifying and treating oil spills is operationally and scientifically challenging and compounded by the difficulty in accurately obtaining real-time measurements of the oil thickness slicks. Here, we present a method that allows precise real-time measurement of oil slick thickness, based on active optical interferometry. A series of laboratory experiments with common hydrocarbon pollutant types, namely crude oil and gas condensate, showed that our method yields precise thickness measurements for slicks in the thickness range 0.382 - 23.3 (μm), with an accuracy of 95%. The novel oil layer thickness measurement system can in principle be adapted for use at sea, which would open the way for real-time thickness measurements that will improve oil-spill mitigation efforts and contribute to our understanding of processes at the ocean-atmosphere interface.
