Paper Abstract

An optical-time-domain-reflectometry based shape sensor is presented. Fibers with air-gap splices at certain known positions are attached to the exterior of a flexible structure. The strain induced in each fiber section due to the bending of the structure is detected by the Optical Time Domain Reflectometer (OTDR) as shifts in the pulses reflected at the splices. The approximate shape of the structure is then determined using the strain information from each fiber section. Experimental results for simple shapes are given, and future directions for determining complex shapes are discussed.
