sample is presented in this article. A π-phase-shifted fiber Bragg grating (π-PSFBG) sensor,
as an accurate and sensitive optical FBG sensor, is used for simultaneously measuring the
strain and temperature of this sample in a fixed cantilever configuration. The central peak
wavelength shift of the transmission spectrum of the π-PSFBG's Bragg wavelength and its
power are used as indicators of strain and temperature of the sample. As a result, the …
