This paper highlights the efforts of the Naval Surface Warfare Center to develop a fiber optic pressure transducer. The initial application for this fiber sensor is to monitor the pressure in the sonar dome of a surface ship. This required a 0 bis 100 pounds per square inch (gage) sensor. This sensor, developed by Luxtron, under a small business innovative research contract, utilizes a vibrating quartz crystal as the transduction mechanism. Changes in the resonant frequency of the quartz crystal as a result of force applied to the crystal is monitored using a simple fiber optic link. This paper discussed the basics of operation and design of the sensor, advantages and disadvantages of this type of sensor, development results to date, and future development plans.
