Abstract

In the past decade a broad range of sensing applications have been reported which utilize optical fiber based sensors. 1''2 These applications range from the measurement of a variety of physical parameters to the quantitative determination of chemical and biochemical species. This paper discusses recent work performed at Eastman Kodak CoiTpany concerning development and testing of fiberoptic sensors in process monitoring and control environments. Topics include sensing mechanisms sensor design environmental considerations and sensor performance characterization in process environments. Sensing mechanisms described inlude optical time domain reflectometer (OTDR) distributed fiber-optic sensing multiplexable reflective fiberpair sensing and photoncorrelation spectroscopy. Distributed fiber-optic sensing applications including temperature pressure strain humidity chemicals and distributed alarms are discussed. Reflective fiberpair sensors described include edge location distance and vibration. Use of photoncorrelation techniques with fiberoptic sensors are also described and process applications of these techniques are presented. 1.
