A fiber-optic Fabry-Perot interferometric chitosan membrane hydrophone for in vivo ultrasound measurements is proposed. The hydrophone is based on a thin chitosan film acting as a low-finesse Fabry-Perot cavity that is formed at the tip of hollow core fiber. Chitosan membrane provides maximum acoust...
