Profile of a fiber from backscattering measurements.
The angular positions of the light-scattering minima obtained from structures placed on flat substrates are closely related to the geometry of the scattering object. We show how the profile of a fiber can be determined, and possible irregularities located, by measurement of the backscattering patterns. An approximate double-interaction model is used to fit the results.
