Acousto-Optic Comb Interrogation System for Random Fiber Grating Sensors with Sub-nm Resolution
The broad-frequency response and nanometer-range displacements of ultrasound detection are essential for the characterization of small cracks, structural health monitoring and non-destructive evaluation. Those perturbations are generated at sub-nano-strain to nano-strain levels. This corresponds to...
