Optimization of Fiber Bundles for improvement in linear operating range of fiber optic displacement sensor

Present paper analyzes three arrangements of fiber optic bundle displacement sensor for improving the linear operating range of sensor. Concentric, random and hemi circular configurations of fiber bundles are examined. These different arrangements are studied for the variation in sensitivity and linear operating range with increase in number of fibers in a bundle. It is simulated in MATLAB and verified experimentally for random, concentric and hemi circular configurations.
