| 摘要 |
Inertially insensitive optical fibre hydrophones are described, utilising materials and configurations to obtain acceleration balanced designs suitable for underwater applications where acceleration is a problem. Balancing and/or insensitivity is obtained both in longitudinal and axially perpendicular directions. Acoustic sensitivity of a coil (2) formed by the fibre is maintained by the properties of materials used to provide a rigid former (4), encapsulant material (3) and secondary material (6) which form the hydrophone. |
