Paper Abstract

A non-contact method was proposed to fingerprint the characteristic of oil-film on water surface based on a scanning white-light interferometer technique. This intensity-based method is stemmed from the facts that the reflections of the oil-film surface and the interface of oil-film on water surface are good enough to form a surface and an interface interferogram, respectively. A criterion is derived theoretically and tested experimentally by carefully calculating the intensity ratio of the central fringes of the surface interferogram and the interface one.
