Description
Summary:碩士 === 逢甲大學 === 電機工程所 === 100 === This paper proposes a method to measure active power using a fiber Bragg grating (FBG) and a piezoelectric actuator (PZT).The deformation of PZT is proportion to the voltage equivalent to the active power to create an axial strain to FBG. The strain will stretch the FBG to cause the center wavelength shift. The reflected spectrum is detected by an Optical Spectrum Analyzer (OSA).Experimental results show that there is a linear relationship between the active power and the displacement of reflective spectrum of FBG.
