We report the results of a study of the performance characteristics of a distributed fiber-optic shape and position sensor.
Strain measurements from distributed fiber Bragg gratings in a multi-core optical fiber multiplexed via the frequency
domain reflectometry technique are used to deduce the shape of the optical fiber. We have measured a range of two- and
three-dimensional shapes using a multi-core fiber with a sensor spacing of 1.0 cm and a gage length of 0.5 cm and have
reported the accuracy and precision of these measurements. A discussion of error sources is also included.© (2006) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.
