| Abstract: | To raise the spectral resolution of fiber-optic Fourier transform spectrometer, a PZT driving power of Fiber-optic phase modulation, composed of a low-frequency signal generator and a high voltage amplifier, was designed. The bode plot and open loop phase shift plot was used to analyze and discuss the stability of circuit thoroughly, when the capacitive loads with higher capacitance were driven. The result of experiment indicated that high spectral resolution of fiber-optic Fourier transform spectrometer could be achieved with the driving power. |
