Abstract

A mathematical model is derived for the focusing method which relates refractive-index and deflection function errors to errors in the measured light intensity. The model predicts that refractive-index measurement noise increases linearly from zero at the outside diameter of the fiber to a maximum value at the center of the core. Measurement errors for the focusing method determined by experiment are in close agreement with predictions obtained using the theoretical model.
