Abstract :
The paper have demonstrated application of an adaptive interferometer based on population gratings in erbium-doped fiber (EDF) for the detection of laser-generated ultrasonic displacements in 20 MHz frequency band. Such interferometer can be particularly attractive for industrial applications because it can be implemented as a simple and robust all-fiber system based on commercial components only.
