摘要：

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 prating wavelength. initial results show microstrain resolution at data acquisition rates of 10Hz.
