LARGE SCALE HIGH MULTIPLEXED OPTICAL FIBER SENSOR NETWORK

摘要

Optical fiber digitally spatial and wavelength domain system for multiplexing a Bragg grating sensor, and incorporates a plurality of optical fiber Bragg grating, respectively, each optical fiber Bragg grating is for reflecting and transmitting light at a corresponding to the distortion corresponding to the center wavelength, means for grating the optical fiber to the first half to an optional center wavelength and to change to correspond to the distortion, and means for irradiating the light source 110 of the broadband optical fiber Bragg grating and, having selected a light position, and the selection of each of the optical fibers, position, and the light having the wavelength separation for supplying independent signal spatially to each optical fiber Bragg gratings in the respective optical fiber, in response to the light from each optical fiber, eunghaeseo the positions of the optical fiber wavelength to separate the wavelength for each optical seomwi the center wavelength and a balancer (136).
