1. An instrument system, comprising:
- an elongate instrument body; and
an optical fiber sensor comprising an elongate optical fiber coupled to the elongate instrument body,wherein a portion of the optical fiber is coupled to the elongate instrument body in a manner to provide slack in the fiber to allow for axial extension of the elongate instrument body relative to the optical fiber.
