1. A method of detecting debris on a surface of a member, the method comprising:

  • heating the member by actuating a de-icing system integral to the member;

    sensing an infrared radiation emitted from a portion of the surface of the member opposite the de-icing system; and

    determining a change in the infrared radiation resulting from the heating of the member by the de-icing system in said heating step, the change being determined as a temporal emission profile of the radiation emitted from the portion of the member, and thereby detecting the presence of debris on the surface of the member.
