Abstract
A sensor for sensing conditions on an object. The sensor comprises a first at least partially reflective surface layer disposed adjacent the object in close conforming relationship with a surface of the object, an intermediate layer, and a second at least partially reflective surface layer. The intermediate layer is disposed between the first at least partially reflective surface layer and the second at least partially reflective surface layer. The intermediate layer can be formed as a solid element, a combination of solid areas and spaces, and as an aerogel.
