SYSTEM AND METHOD FOR SENSING MANY FIBER SENSORS USING TIME-DIVISION MULTIPLEXING AND WAVELENGTH DIVISION MULTIPLEXING

摘要

A system and method for discriminately measuring the response of a plurality of spatially separated fiber sensors positioned along an optical fiber using a sweep of electromagnetic radiation. Each fiber sensor affects the transmission of a particular wavelength of electromagnetic radiation and the particular wavelength affected by a given fiber sensor is dependent on at least one environmental property of the given fiber sensor. By detecting the particular wavelength affected by a given sensor, it is possible to determine the environmental property of the given sensor.
