Abstract
In an embodiment, an optical ice detection method is provided. The method includes contacting a multilayer structure with water under conditions effective to form ice, the multilayer structure comprising an optically transparent or semi-transparent material disposed over at least a portion of a material probe. The method further includes performing Raman spectroscopy on one or more of the material probe, water, or ice to obtain Raman spectra, detecting a shift in the Raman spectra, and calculating ice-induced strain in the material probe. Apparatus for optically detecting ice are also provided.
