Abstract :
A linearly configured fiber-optic acoustic sensor has been developed by embedding a single-mode fiber in a polyurethane cylindrical layer. The acoustic sensitivity was studied in the range of 0.75-10 KHz and was found to be frequency independent and significantly higher than that of a free suspended fiber or a solid mandrel fiber sensor. A comparison is mace between this sensor and air-backed fiber-optic mandrel sensors
