Fiber optic displacement sensors (FODS) are studied and analyzed by using different configurations (Atsushi and Kohichi, 1996; Faria, 1998; Buchade and Shaligram, 2006) [1,2,6]. Mathematical models developed for these configurations use analytical methods and techniques. It is observed that these models are useful for a specific geometrical arrangement of fibers and reflector and are not useful for any variation in configuration. Hence it is necessary to develop a mathematical model which is independent of configuration of the fiber optic sensors. This paper discusses development of such generalized model which is useful for studying and analyzing any configuration and scenario of fiber optic sensor. The model is expected to be useful in analyzing manufacturing tolerances as well as effects of the geometrical parameters on performance of the sensor.
