The Science

To detect oil slicks as thin as a single micron from up to 10m above the water, the ROW pulses a UV beam at the surface and excites any oil molecules in the target area. Using oil’s native fluorescence, ROW is calibrated to identify the specific wavelength signal of oil and send out an alert.

After 20 years of developing remote-sensing systems, LDI has mastered the technology better than anyone else.

Industry-leading Sensitivity – 1µm

Advanced software algorithms are calibrated to detect oil down to single-micron layers and minimise false alarms.
