Method and apparatus for sensing underwater signals |
摘要 |
Methods and apparatuses are disclosed that assist in sensing underwater signals in connection with geophysical surveys. One embodiment relates to a transducer including a cantilever coupled to a base. The cantilever may include a beam and a first coupling surface angularly oriented from the beam, and the base may include a second coupling surface angularly oriented from the beam and substantially parallel to the first coupling surface of the cantilever. The transducer may further include a sensing material coupled between the first coupling surface of the cantilever and the second coupling surface of the base. |

1. A transducer, comprising:
a cantilever coupled to a base, the cantilever comprising a beam and a first coupling surface angularly oriented from the beam and defined by a forward end of the cantilever, and the base comprising a second coupling surface angularly oriented from the beam and substantially parallel to the first coupling surface of the cantilever; a sensing material coupled between the first coupling surface of the cantilever and the second coupling surface of the base; and a tine that couples the cantilever to the base, wherein the tine is configured to reduce the cross-axis sensitivity of the transducer and to enhance sheer stress applied to the sensing material; wherein one or both of the first or second coupling surfaces defines an acute or obtuse angle with respect to a longitudinal axis of the beam. |
