Abstract
A fiber optic pressure sensor is being developed for the Naval Surface Warfare Center- Dahlgren Division for use in measuring the pressure within sonar domes of Naval ships. The sensor comprises a quartz crystal tuning fork and force transduction mechanism such that the frequency of the quartz crystal is proportional to pressure within the sonar dome. An optical fiber interface is used to transport light to power the quartz crystal and measure its frequency. These sensors are compatible with the fiber optic cable plant of Naval ships.
