Abstract

Fiber Bragg gratings are the most popular type of optical fiber sensor. However, its commercial use is frequently limited by high cost and complexity of the interrogation unit. Here, an interrogator based on a femtosecond laser written silica scattering chip is designed and implemented. Such device can directly reconstruct strain, from the scattering speckle patterns, with a resolution of 70 µϵ (microstrain) within the range of 180-700 µϵ, limited by the slippage of the fiber coating, with the potential to be reduced with the system improvements.
