摘要
An optical system for detecting perturbations indicative of the performance of the piece of equipment being monitored is disclosed. The optical system comprises sensors each of which use Bragg gratings induced therein and wherein the Bragg gratings are arranged into a preselected distribution and each Bragg grating returns, when subjected to incident light, a narrowbeam signal identified by a predetermined wavelength. The optical system utilizes at least one interferometer whose operation is interlinked with optical multiplexing techniques, such as differentiate-cross-multiplying and time-division multiplexing.
