Abstract: The present invention is directed to a method for characterizing an optical preform. To achieve this, the present invention provides a three-dimensional map of the refractive-index distribution within a boule or an optical preform. The three-dimensional map of the refractive-index distribution allows device manufacturers to better predict the performance of the optical device. The three-dimensional map also allows device manufacturers to determine the best orientation of the preform during device extraction.
