Abstract
An apparatus for estimating a shape, the apparatus including: an optical fiber configured to conform to the shape and having a first core offset from a centerline of the optical fiber, the first core having an optical characteristic configured to change due to a change in shape of the optical fiber wherein a change in the optical characteristic is used to estimate the shape. A method for estimating a shape is also disclosed.
Claims21
An apparatus for estimating a shape of a structure, the apparatus comprising:
- an optical fiber non-rigidly attached to the structure, the optical fiber configured to conform to the shape and comprising a first core offset from a centerline of the optical fiber, the first core comprising an optical characteristic configured to change due to a change in shape of the optical fiber wherein a change in the optical characteristic is used to estimate the shape.
A method for estimating a shape of a structure, the method comprising:
- illuminating an optical fiber non-rigidly attached to the structure, the optical fiber configured to conform to the shape and comprising a first core offset from a centerline of the optical fiber, the first core comprising an optical characteristic configured to change due to a change in shape of the optical fiber;
- and
- receiving light signals resulting from the illumination to estimate the shape;
- wherein the light signals comprise information related to a change in the optical characteristic.
A non-transitory computer-readable medium comprising computer-executable instructions for estimating a shape of a structure by implementing a method comprising:
- illuminating an optical fiber non-rigidly attached to the structure, the optical fiber configured to conform to the shape and comprising a first core offset from a centerline of the optical fiber, the first core comprising an optical characteristic configured to change due to a change in shape of the optical fiber;
- and
- receiving light signals resulting from the illumination to estimate the shape;
- wherein the light signals comprise information related to a change in the optical characteristic.
