ABSTRACT:
An ice monitoring and detection system for determining the presence and thickness of ice on a surface is provided. The system includes an imaging device which includes at least one lens for providing image signals of the surface. The imaging device is operable in a predetermined portion of the electromagnetic spectrum. Image signals from the surface are polarized into discrete polarization changes responsive to the camera receiving image signals proportional to amplitude modulated signals generated by the presence of ice. A processor is provided for converting the modulated signals into discrete polarization changes and for obtaining the difference between the discrete polarization changes which is proportional to the amount of ice on the surface. An indication device provides an output corresponding to the difference between the discrete polarization changes. The difference is indicative of the presence and amount of ice on said surface.
