摘要
Fiberoptic sensors of various configurations are provided for measuring the magnitude of the electric or magnetic fields, and thereby the power, at local points within a relatively high-power electromagnetic heating environment such as occurs, for example, in a microwave oven or an industrial microwave processing chamber. Each type of sensor includes one element that is heated by either the oscillating electric or magnetic field, and an optical temperature measuring element positioned to be heated by the first element, its temperature being optically determined by an instrument to which an opposite end of the optical fiber length is connected.
