Abstract

In this paper, we propose two optical fiber sensing applications based on the pulse selection technique, in which an acousto-optic modulator (AOM) is employed to generate optical pulses and to choose the pulses traveling back to it. Firstly, we propose an interferometer configuration with optical path difference (OPD) amplified, which offers an alternative way to increase the interrogation resolution and develops some potential sensing applications which require high sensitivity. By adjusting the repetition interval, we can select the pulses which travel along the corresponding arms of the interferometer for any given trips. Secondly, we designed a Fiber Bragg Grating (FBG) sensing system with intelligent sensor management, which offers two work modes and improves the availability of information.
