A simple FBG sensor for strain-temperature discrimination

A simple sensor using half the length of a 3‐cm fiber Bragg grating embedded on a cantilever is proposed for the simultaneous measurement and discrimination of strain and temperature. The response of the sensor is linear from 30 to 200°C, and its strain and temperature sensitivities are found to be...

Description
Summary:A simple sensor using half the length of a 3‐cm fiber Bragg grating embedded on a cantilever is proposed for the simultaneous measurement and discrimination of strain and temperature. The response of the sensor is linear from 30 to 200°C, and its strain and temperature sensitivities are found to be 3.38 pm/μm 19.05 pm/°C, respectively. © 2011 Wiley Periodicals, Inc.
