摘要：

A newly developed fiber-optic pressure sensor for gas turbine applications is described in this paper. The sensor is based on Self-Calibrated Interferometric/Intensity-Based (SCIIB) fiber optic sensor technologies. In addition to the generic fiber sensor advantages, the new sensor was also shown to have all the distinct advantages of interferometric and intensity-based sensors while their disadvantages are significantly reduced. The sensor has a frequency response of similar to 100 Mit, and can be operated at temperatures up to 700 degrees C. The sensor was tested in simulated flow conditions similar to that found in a gas turbine engine. Excellent agreement was obtained in the measured pressure comparing the fiber-optic sensor to a conventional high frequency, semiconductor based pressure transducer.
