We describe a novel optical acoustic detector based on a bias-controlled fiber Fabry–Perot interferometer. The detector has a broad bandwidth from 10 Mhz to a few gigahertz and higher sensitivity than conventional systems, which are useful for noncontact characterization of microsamples based on laser ultrasound.
