摘要

We report on a study of vibration measurements of a gas turbine via fiber optic sensor based on a Mach-Zehnder interferometer. The experiment allows controlling the rotation frequency and detecting acoustic signals from some defects in construction. Phase unwrapping scheme of fiber interferometer and spectrogram analysis provide the measurement information.
