  • Abstract
    The authors demonstrate for the first time an electronic lock-in system using an acousto-optic tunable filter (AOTF) to track the wavelength of a fibre Bragg grating. The change in the system output is proportional to the change in grating wavelength. Initial results show microstrain resolution at data acquisition rates of 10 Hz
