We suggest combining several optical methods for remote sensing and characterization of crude oil films and emulsions. These are coherent fringe projection illumination CFP, holographic in-line interferometry HILI, and laser-induced fluorescence. The combined methods of CFP and HILI are described in the frame of coherent superposition of partial interference patterns. It is shown that in addition to detection and identification of oil, laser illumination in the green-blue region can also degrade oil. This finding indicates that properly structured laser clean-up can be an alternative method of decontamination.
