Characterizing structural and geometric properties of optical fibers

A processing system, comprising:

• a memory comprising computer-executable instructions;
• and a processor configured to execute the computer-executable instructions and cause the processing system to:
• generate a coordinate point representation of an image comprising a cross-section of an optical fiber, the generated coordinate point representation comprising a series of edge points;
• determine, based on the series of edge points, a circular primary structure within the generated coordinate point representation having a largest diameter;
• generate a first best-fit rounded shape corresponding to a series of inner edge points and a second best-fit rounded shape corresponding to a series of outer edges points of the circular primary structure;
• detect one or more circular sub-structures within the first best-fit rounded shape;
• for each respective detected circular sub-structure of the one or more detected circular sub-structures, generate a series of subsequent best-fit rounded shapes corresponding to respective inner edge points and respective outer edge points of the respective detected circular sub-structure;
• and
• calculate a structural property of the optical fiber using values based on at least one of the generated first best-fit rounded shape, second best-fit rounded shape, and subsequent best fit rounded shapes.

A computer program product embodied on a computer-readable medium comprising program code for performing a method, the method comprising:
