Abstract:
A method of analyzing a polarization-maintaining (PM) optical fiber includes illuminating a side of the PM optical fiber, physically rotating the PM optical fiber and measuring light intensity of light transmitted through the PM optical fiber to obtain an image profile, mathematically shifting the image profile at incremental rotation angles, expanding the image profile at each rotational angle into a Fourier series profile, and determining points of symmetry of the PM optical fiber based on the Fourier series profiles.

Claim (Index 1):
A method of analyzing polarization-maintaining (PM) optical fibers, comprising:\n illuminating a side of each of a first and second PM optical fiber; physically rotating each of the first and second PM optical fiber and measuring light intensity of light transmitted through each of the first and second PM optical fiber to obtain an image profile; mathematically shifting the image profile of each of the first and second PM optical fiber at incremental rotation angles; expanding the image profile of each of the first and second PM optical fiber at each rotational angle into a Fourier series profile, each Fourier series including a set of Fourier coefficients a n  and b n ; and determining a ratio value R for each set of Fourier coefficients a n  and b n  of the Fourier series profiles; determining points of symmetry of each of the first and second PM optical fiber based on the R values of the Fourier series profiles; and aligning the first and second PM optical fibers based on the points of symmetry.
