Abstract

A novel temperature-independent FBG-type torsion sensor has been proposed and analyzed. Two FBGs with different Bragg wavelengths are symmetrically bonded to the surface of the torsion beam with an identical angle. This sensor is able to achieve torsional angle measurement over the range from -40° to +40° without suffering from the influence of temperature within the range between -15°C and 75°C.
