Multiplexed Fiber Bragg Grating Interrogation System Using a Modulated Fiber Bragg Grating and the Tunable-Filter Method

This paper describes the use of a mechanically modulated fiber Bragg grating (FBG) to address FBG sensors using the tunable-filter method. A demonstration of FBG sensors multiplexing using this interrogation method is also presented, where the tunable FBG is used to scan the spectral operating range of the sensors. All the FBG used in this paper do not need to match their center wavelengths
