Integrated diagnostics for Navy fiber optic systems

Based on current Navy efforts to incorporate fiber optic technology in 21st century Navy ships, the Navy Metrology R&D program has sponsored four R&D projects aimed at the development of new calibration technology to support anticipated Navy shipboard fiber optic systems. New calibration technology is needed to lower the cost and manpower requirements of supporting large shipboard fiber optic systems by conventional calibration methodologies. This paper will present accomplishments of those four R&D projects. The objective of one project was to perform a built-in-calibration design implementation study for fiber optic sensors. The recommended built-in-calibration implementation strategies will be presented. A follow-on project's objective was to develop a polarization based fiber optic temperature sensor utilizing a variable wavelength light source to achieve calibration. The methodology for using wavelength to calibrate a polarization based sensor will be presented. The third project's objective was to develop a fiber optic pulse characterization system for monitoring the health of fiber optic communication systems (both voice and data) by analyzing the characteristics of the optical pulses generated by such systems. The performance characteristics of this device will be presented. The final project's objective was to develop a method to calibrate a fluorescent based fiber optic biosensor capable of detecting the presence of hazardous materials in environmental samples in nanogram per milliliter quantities. A method under investigation of applying built-in-calibration to calibrate this sensor will be presented.
