Research abstract
RESEARCH LEADING TO AN ABSOLUTE THERMOMETER WITH A FIBER OPTIC READOUT IS PROPOSED. THE BASIC SENSING ELEMENT IS A SHORT LENGTH OF SAPPHIRE. UNDER A PREVIOUSLY FUNDED EFFORT, OPTRA HAS DEMONSTRATED THAT THE OPTICAL BIREFRINGENCE OF SAPPHIRE IS HIGHLY PREDICTABLE AND A NEARLY LINEAR FUNCTION OF TEMPERATURE. READOUT OF THE BIREFRINGENCE WOULD BE VIA A FIBER OPTIC LINK USING OPTRA'S UNIQUE 2-FREQUENCY HETERODYNE LASER. THE USE OF A SAPPHIRE ELEMENT PROMISES A SENSOR HIGHLY TOLERANT TO THE SEVERE ENVIRONMENT INSIDE A TURBINE ENGINE IN TERMS OF EROSION, CORROSION AND VIBRATION. ITS SMALL SIZE SHOULD CAUSE IT TO ONLY MINIMALLY INTERFERE WITH THE GAS FLOW. FOR THIS SPECIFIC EFFORT THE MAIN EMPHASIS WOULD BE CHARACTERIZING THE FIBER OPTIC LINK AND THE EFFECTS OF VIBRATION ON THE TRANSDUCER ELEMENT.
