Abstract
The forward scattering pattern from a transversely-illuminated polymer-coated optical fiber can be used to insure well-centered coatings on optical fibers. A simple interpretation of the scattering pattern provides an error signal to guide compensatory coating cup alignment. For polymers coating materials with a refractive index higher than that of silica, the scattering pattern contains caustic surfaces. If the coating is eccentric in a direction perpendicular to the incident rays, the positions of the caustic surfaces vary monotonically with eccentricity.
