Abstract

An all fiber temperature sensor based on intensity measurement is designed, by using long period fiber grating (LPG) as sensor element and using tunable Er-doped fiber ring laser as optical source. The measured temperature sensitivity of LPG is 0.086 nm/°C, which is about 8.2 times higher than typical value for a normal fiber Bragg grating. In the temperature range of 74 °C, the loss of the laser is linear with the measured temperature and the linearity can be repeated well. The resolution of temperature measurement is 0.1 °C.
