| Abstract: | The cross-sensitivity of the strain and temperature is a main problem of the fiber Bragg grating(FBG) sensor in applications.The principle of synchronous measurement of the temperature and strain by using the dual fiber Bragg grating(FBG) has been introduced.A dual FBGs system for measuring the temperature and the strain has been designed and the temperature and strain sensing performance of the dual FBGs system has been verified.The results showed that the dual FBGs system had the ability to measure the mu... |
