摘要:
A new type of hydrophone based on high-birefringence fiber loop mirror (HiBi-FLM) is proposed and demonstrated. The sensing part is a section of high-birefringence fiber wound onto a hollow metal cylinder fiber. A narrow band light source is used and the detection is done by measurement of light intensity. The hydrophone is theoretically researched and experimentally verified. The hydrophone is 32 times more sensitive than FBG hydrophone and has the advantages of polarization indent, cheap cost and easy interrogation.
