Abstract

Fiber Bragg grating based ultrasound sensors has been receiving continuous attention from science and industry. It is of great potential in medical imaging, oil exploration, etc. In this paper, we construct an all fiber ultrasound sensing system with cascaded phase-shifted FBG and a normal FBG. Correlation algorithm is used to improve the detection sensitivity based on data acquisition board and virtual instrument LabVIEW. In the experiment, the system sensitivity is calculated as and the dynamic range of the system is 79.33dB
