Techniques of gradient index optics have been studied for use in determining real time degradation of anti-icing fluids during ground icing events on aircraft. Experiments have shown three separate measurement approaches which can yield important different information about the makeup of the thin anti-icing film used. These include critical angle refractometry at the solid-liquid interface, analysis of the secondary reflection from the liquid-air interface, and determination of critical angles at internal positions within the deicing film. This paper will discuss results of our tests in terms of the performance and limitations of the techniques.
