Solid-State interferometric interrogator and multiplexer for high-speed dynamic and absolute FBG wavelength measurement ABSTRACTWe present a solid-state FBG array interrogator and multiplexer capable of determining absolute FBG wavelengths and of providing high-speed, high-resolution static and dynamic measurements. Using a described procedure, deployable on multiplexing passive-interferometric schemes, the system is able to determine initial sensor wavelengths and thereafter track wavelength changes with interferometric resolution. The scheme allows high-resolution interrogation of FBG sensor arrays to be applied to many industrial applications, where previously the lack of combined absolute and quasistatic wavelength measurement precluded the use of interferometric techniques. Using a preliminary laboratory embodiment, we demonstrate a wavelength determination accuracy of <0.3 nm and a measurement resolution of 10 fm/√Hz, and propose pathways to improved performance and miniaturisation.

“…183,184 High-speed systems that are not commercially available have also been proposed. [185][186][187] On the other hand, the sensor reliability can be easily improved through the multiplexing of FBGs, acquiring signals from several different places of the body, addressing all the FBGs with one optical fiber, and handling such an arrangement with one interrogation unit.…”
