| titleOfInvention |
Flexible microsphere coated piezoelectric acoustic sensor apparatus and method of use therefor |
| abstract |
Sensors used in mapping strata beneath a marine body are described, such as in a towed array. A first acoustic sensor uses a piezoelectric sensor mounted with a thin film separation layer of flexible microspheres on a rigid substrate. Additional non-acoustic sensors are optionally mounted on the rigid substrate for generation of output used to reduce noise observed by the acoustic sensors. A second sensor is a motion sensor including a conductive liquid in a chamber between a rigid tube and a piezoelectric motion film circumferentially wrapped about the tube. Combinations of acoustic, non-acoustic, and motion sensors co-located in rigid streamer housing sections are provided, which reduce noise associated with different sensor locations. |
