Abstract
We report a fiber sensor capable of simultaneously measuring temperature and strain. A fiber Bragg grating (FBG) was incorporated in a Lyot fiber filter (LFF) by fusion splicing a section of high birefringence fiber (PM fiber) with an FBG and then placing them between 2 polarizers. Measured in the transmission mode, the fringe resulted from the LFF and the resonance wavelength dip of the FBG has different responses when a variation of temperature or strain is applied. The proposed device can therefore measure both strain and temperature simultaneously.
