Abstract
A sensor device includes a flexible instrument (20) including a lumen (22). A plurality of shape or strain sensing optical fibers (14, 16, 18) is integrated in the flexible instrument in the lumen and extends over a length of the flexible instrument. The plurality of optical fibers is configured to measure movement relative to one another to sense a change in distance between the plurality of optical fibers to detect a state of a reconfigurable portion (24) of the flexible instrument.
