The state of fiber optic sensor technology is reviewed from the point of view of the potential user. Industrial opportunities and applications are emphasized. An attempt is made to understand why the technology is not seeing widespread acceptance. Issues of general discussion include technical, economic, and other disadvantages (and advantages) of fiber optic sensors, such as maintenance, reliability, and user training. Comparisons with the existing competition of electronic sensors are examined. Present shortcomings of fiber sensor technology are emphasized along with user requirements that must be addressed if fiber optic sensors are to see wide application.
