Abstract

We demonstrated the effects of multiplexing interference on the reflected spectra of multi-point fiber Bragg Gratings (FBGs) with common-path interferometer multiplexing. This paper is described that our system is able to measure the reflected spectra and the reflected wavelengths ever 2 s without the effects of multiplexing interference by introducing offset fiber.
