摘要：
Simultaneous measurement of temperature and force using a single fiber Bragg grating based on broadened reflection spectrum is proposed and demonstrated. The wavelength peak shift and the bandwidth broadening with the change of temperature and force allow discrimination between the temperature and force effects. Standard deviation errors of 1.8 degrees C and 0.16N have been obtained with temperature and force ranges of up to 20 similar to 100 degrees C and 0-8N, respectively.
