E. Belotserkovsky et al., INFRARED FIBEROPTIC TEMPERATURE CONTROL OF THE HEATING PROCESS IN A MICROWAVE-OVEN, IEEE transactions on microwave theory and techniques, 42(5), 1994, pp. 901-903
An infrared (IR) fiberoptic temperature sensor was used to monitor of
non-uniform heating of biological samples. The developed system allows
the monitoring of temperature with an accuracy of +/-0.5-degrees-C an
d can be very useful for medical, industrial and domestic applications
