Ultrasound sensing based on an in-fiber dual-cavity Fabry – Perot interferometer

Highly sensitive and broadband ultrasound (tens of megahertz) detectors can extend the capabilities of photo-acoustic imaging in biomedical application and nondestructive test inspection. Here ultra-compact fiber-based multi-mode dual-cavity Fabry – Perot interferometer (DC-FPI) ultrasound ...
