Dyott et al, Elect. Lett. vol. 15, no. 13, pp. 380-382, 1979). The work was transferred to Andrew at Orland Park, Illinois in September 1979. The subsequent development in 1982 of the D fiber (R.B. Dyott and P.F. Schrank, Elect. Lett., vol. 18, no. 22, pp. 980-981, 1982), which made the evanescent field of the waveguide accessible, resulted in a fused directional coupler (R.B. Dyott and J. Bello, Elect. Letters, vol. 19, p. 601, 1983) and a fiber polarizer (R.B. Dyott, Optics Letters, vol. 12, p. 287, 1987); the bones of fiber sensors. The first packaged gyro was produced in 1987 as a potential replacement for the mechanical gyros that were being used for antenna stabilization in ships of the US Navy. However it was limited by the very short lifetime of its superluminescent diode light source. This paper summarizes gyro development and production, both at Andrew and at KVH Industries which acquired the gyro product line and production facilities from Andrew in 1997.","PeriodicalId":147710,"journal":{"name":"2002 15th Optical Fiber Sensors Conference Technical Digest.

The high sensitivity of the FFPI sensors allowed for the measurement of strain forces affecting roller element bearings. Tests were carried out to compare the time waveforms for load comparisons and their respective spectra of generated bearing frequencies to expected values of such bearings. Further tests were conducted to assess the effects of imbalance added to the shaft, rotational speed, and impulses on the rotor system. Positions of observed spectral peaks show good agreement with predictions. These results indicate that fiber optic sensors can provide a unique capability for bearing monitoring in today's machinery.","PeriodicalId":147710,"journal":{"name":"2002 15th Optical Fiber Sensors Conference Technical Digest.

In the last few years there has been considerable interest in the telecommunications community in deploying arrayed waveguide gratings (AWGs) produced in a range of technologies in a variety of roles. We feel it is therefore surprising that there have been very few reports of research into using AWGs for sensing. In this paper we consider some possible roles for these devices in interrogation systems for interferometric and fibre Bragg grating (FBG) sensors.","PeriodicalId":147710,"journal":{"name":"2002 15th Optical Fiber Sensors Conference Technical Digest.

The wavelength-encoded nature of the reflected signals from FBGs allows for absolute strain measurement and for multi-point operation based on wavelength division multiplexing (WDM). To measure strain variation with good accuracy, detection of the small shift in the Bragg wavelength is essential. In this paper, we report the use of a digital matched filter (DMF) for improving the wavelength detection accuracy. The DMF technique has been used extensively in image processing and pattern recognition for the detection of weak signals in a noisy environment. We apply it here for the detection of Bragg wavelength in FBG sensors when the SNR is low.","PeriodicalId":147710,"journal":{"name":"2002 15th Optical Fiber Sensors Conference Technical Digest.

Principal activities involve the commercialization of this technology in two distinct categories: (1) interferometric demodulation; and (2) white-light coherence domain systems. Instead of focusing on specific end-use sensing systems, we have targeted commercialization of the elements of these systems involved with the interrogation of the sensors and accurate conversion of (optical) sensor information into electronic formats. The motivating concept is that commercialization of interrogators will address multiple markets with common designs, leading to cost reduction through higher volume manufacturing. This business approach pre-supposes that such standardization is acceptable to and meets the needs of the (fiber) sensing industry. This discussion reviews the commercialization efforts for the two interrogator categories.","PeriodicalId":147710,"journal":{"name":"2002 15th Optical Fiber Sensors Conference Technical Digest.
