Electromagnetic (microwave or radio frequency) field‐induced heating is used in industrial, medical, and domestic applications. In most cases, efficient, rapid, and controllable heating is needed. A problem with this heating modality is the difficulty in gaining an accurate measurement of temperature in the presence of a strong electromagnetic field. A simple infrared fiber‐radiometer system has been developed for thermometry in the presence of these strong electromagnetic fields. The radiometer was used to measure temperatures in the range 0–70 °C, with an accuracy of ±0.5 °C. The signal obtained varied almost linearly with temperature.
