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 5):
An interrelation profile analysis (IPA) apparatus configured to analyze polarization-maintaining (PM) optical fiber, comprising:\n a light source configured to emit light towards each of a first and second PM optical fiber; a fiber rotating unit configured to physically rotate each of the first and second PM optical fiber; a light receiving unit configured to receive the light passing through each of the first and second PM optical fiber; and an IPA profile calculating unit configured to obtain an image profile of each of the first and second PM optical fiber based on light intensity of the received light, mathematically shift the image profile of each of the first and second PM optical fiber at incremental rotation angles, expand 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 , determine a ratio value R for each set of Fourier coefficients a n  and b n  of the Fourier series profiles, determine points of symmetry of each of the first and second PM optical fiber based on the R values of the Fourier series profiles, and align the first and second PM optical fibers based on the points of symmetry.
