Details of a method of determining the refractive index distribution of graded‐index optical fibers based on interference microscopy are discussed. Sample preparation techniques, observational methods, and data reduction and analysis by a computer fitting program are described. Representative data for optical fibers prepared by chemical vapor deposition are shown.
