Abstract
Fiber sensors have found numerous industrial, military and civil applications in the last decade. These sensors possess small size and high sensitivity, are immune to electromagnetic interference and can be easily modified for distributed or multi-parameter measurement. The extrinsic Fabry-Perot interferometric (EFPI) fiber optic sensor, though it retains all these advantages, still has a few limitations which have prevented its large scale commercialization as an effective strain gage. We discuss these limitations and report the status of manufacturing techniques. Recent progress in the development of extrinsic Fabry-Perot interferometric sensor is reported. Techniques for absolute measurement are demonstrated and adhesives and endface coatings for sensor fabrication are analyzed. Many different applications are presented along with discussions of packaging and attachment issue problems and solutions. The applications include high temperature, low temperature, and harsh environments such as Mach 6 wind tunnels and rock drills.
