Polarization: A Key to an Airborne Optical System for the Detection of Oil on Water

John P. Millard, John C. Arvesen

Open publisher page 13 citations

Abstract

Skylight polarization, which varies with the position of the sun in the sky, influences the contrast of oil on water. Good contrast is most consistently obtained by viewing in azimuth directions toward or away from the sun. Contrast is enhanced by imaging selected polarization components and by taking the difference between orthogonal polarization components.
