Paper Abstract

Operation of an optical fiber sensor based on an in-fiber Fabry-Perot interferometer using chirped fiber Bragg gratings is examined in the pulse-position modulation scheme, especially for mechanical vibration measurement. Emphasis is placed on the ability to measure vibration of larger amplitude. Although the magnitude of vibration that can be measured with a single Fabry-Perot resonance peak is rather limited, the limitation is expected to be overcome by use of multiple resonance peaks in the operation. The experiment with five resonance peaks shows the successful operation of the sensor and therefore the validity of the method proposed.
