Abstract
OPTRA PROPOSES TO DEVELOP AND DEMONSTRATE A FAST HIGH PRESSURE TRANSDUCER BASED ON THE STRESS-OPTICAL EFFECT IN A SINGLE OPTICAL CRYSTAL. THE SMALL SIZE OF THE SENSOR RESULTS IN A FAST RESPONSE, AND ITS MONO-LITHIC NATURE--WITH SENSING AND TRANSDUCING FUNCTIONS COMBINED IN ONE AND THE SAME ELEMENT--SHOULD AVOID RECIPROCITY FAILURES COMMON TO TRANSDUCERS WHERE THESE FUNCTIONS ARE DISTINCT. THE STRESS INDUCED OPTICAL BIREFRINGENCE WILL BE READ OUT BY OPTRA'S UNIQUE 2-FREQUENCY HETERODYNE LASER VIA AN OPTICAL FIBER LINK. THE READOUT IS INHERENTLYDIGITAL AND INDEPENDENT OF SIGNAL STRENGTH. THE BASIC SIMPLICITY OF THE SENSOR, AND ITS PASSIVE NATURE, SHOULD GIVE IT THE POTENTIAL OF IT BEING USED AS A "ONE-TIME" COMPONENT.
