Abstract

About fifteen years ago, it became pretty clear that a combination of fiber optic and photonic technologies offered an opportunity to use light to perform almost any of the functions traditionally performed with wire and electronics--as well as to gain a number of unique advantages in the process. Sensors were quickly recognized as prime candidates for conversion to optics because the new technologies promised to eliminate noise susceptibility, a problem that has always plagued instrumentation engineers. As a bonus, the new technology also appeared to make the long-sought true digital sensors a practical reality. The benefits appeared so attractive that nearly all major suppliers and users of sensors began some kind of program to get on the bandwagon. The ensuing worldwide explosion of activity resulted in literally thousands of technical papers and patents, but a discouragingly small number of practical off- the-shelf devices. This paper will review the field of fiber optic position sensors, will categorize the various types, will discuss their relative advantages and disadvantages, and will outline the problem areas which still remain to be solved before the technology is likely to find the predicted widespread use.
