1. A medical device system comprising:
a medical device comprising an optical fiber having one or more core fibers, each of the one or more core fibers including a plurality of sensors distributed along a longitudinal length of a corresponding core fiber, each sensor of the plurality of sensors configured to:
(i) reflect a light signal of a different spectral width based on received incident light, and
(ii) change a characteristic of the reflected light signal based on strain experienced by the optical fiber; and
a console including one or more processors and a non-transitory computer-readable medium having stored thereon logic, when executed by the one or more processors, causes operations including:
providing an incident light signal to the optical fiber;
receiving reflected light signals of different spectral widths of the incident light by one or more of the plurality of sensors;
processing the reflected light signals associated with the one or more of core fibers to determine a three-dimensional (3D) shape of the optical fiber;
detecting a predetermined subshape of the 3D shape;
defining a reference plane in accordance with the predetermined subshape, wherein the reference plane defines a viewing perspective of the 3D shape; and
orienting the reference plane in 3D space for rendering an image of the 3D shape on a display.
