ABSTRACT:
An optical system for detecting perturbations indicative of the performance f 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.
