1. A sensor for measuring the temperature of a surface of an object, comprising:

  • a cap having an end wall of thermally conducting material and shaped to conform to a shape of the object surface to be measured;

    a surface on an inside of the end wall of the cap that emits electromagnetic radiation having a detectable optical characteristic that is functionally dependent on the temperature of the end wall;

    a light waveguide disposed generally orthogonal to the cap and in optical communication therewith; and

    a resilient member connected to the cap in a manner to urge the cap toward the surface of the object in a manner allowing a limited degree of directional freedom with respect to the waveguide, thereby causing the cap outside surface to firmly engage the object surface when positioned in contact therewith.
