Abstract
In this paper, we present the readout process of two low reflectivity FBG sensors based on a multimode multiheterodyne source generated with a continuous wave laser. We read two independent Fiber Bragg Grating sensors with slightly different Bragg wavelengths that are experiencing periodic vibration and temperature changes.
