摘要：
In this paper we have studied the performance of a high-temperature packaged sensor based on Regenerated Fiber Bragg Gratings (RFBGs). The packaging consists of a two-bore ceramic tube and a 1.5 mm-thick metal casing. The optical response of packaged and unpackaged RFBG sensors for temperature measurements up to 1100 degrees C have been evaluated and compared to each other. Especial attention has been placed on possible residual hysteresis in the thermo-optical response after several temperature cycling tests. The response and recovery times of the packaged sensor has been also measured. The former has been found to be comparable to that of commercial thermometers based on conventional thermocouples.
