Abstract

A fiber specklegram sensor for multichannel sensing is presented. Analyses and experiments show that a fiber specklegram sensor (FSS) is highly sensitive to the modal phasing variation of a multimode-sensing fiber. It is shown that the FSS is less vulnerable to environmental factors than the two-arm interferometric fiber-sensing technique. Because the FSS processes a narrow spectral bandwidth, it is particularly suitable for wavelength multiplexing. One of the major advantages of the FSS must be the multiplexing capability, in which multiparameter sensing can be realized in a single fiber. Applications of the FSS system to acoustic-sensing array, structural fatigue monitoring, and smart emission detection are also discussed.
