Various embodiments and methods relating to an optical fiber curvature measurement system are described herein. The optical fiber curvature measurement system includes a controller and a rotation stage. The rotation stage includes a central axis, a first end, and a second end. The central axis extends from the first end to the second end of the rotation stage. The rotation stage includes an optical fiber channel extending from the first end of the rotation stage to the second end of the rotation stage. The rotation stage is operationally coupled with the controller and configured to rotate about the central axis of the rotation stage. An optical fiber may be positioned within the optical fiber channel. The optical fiber curvature measurement system also includes a light source positioned to emit light onto the optical fiber channel at an oblique angle from the central axis of the rotation stage.
