Abstract
A four-element fiber Bragg grating acceleration sensor array is presented in this paper. The system combines an unbalanced Mach-Zehnder interferometer and three coarse wavelength division multiplexers (WDMs). The totally passive scheme has the advantages of high operation frequency and loose requirements for the working environment. An acceleration resolution of better than 0 . 012 m / s2 sqrt(Hz) for the four channels is achieved.
