STUDY OF TEMPERATURE-MEASUREMENT ERROR OF A FIBEROPTIC PROBE IN A MICROWAVE FIELD

When a fiber-optic thermometer is placed in a microwave field to measu re temperature, there will be energy loss due to electromagnetic inter action, which will certainly bring error in the measured temperature, within the sensor. In this article we have simplified the sensor to a finite-length cylinder, and calculated the energy loss and temperature error. In addition, the measurement error of temperature is studied f or a practical thermometer transducer fiber-optic sensor placed in a m icrowave field. (C) 1995 John Wiley & Sons, Inc.
