Refractive Index Measurement of Fibers Through Fizeau Interferometry

Abstract

The optical properties of transparent polymer fibers are investigated for use in transparent composite materials using a Fizeau interferometer. Refractive index and thermo-optic measurements are performed for off-the-shelf and internally manufactured fibers. The interferometer is shown to produce accurate, repeatable results for fibers with a cross-sectional area of over 500 m2. Results show that manufacturing variables can have significant effects on the optical properties of polymer fibers, particularly birefringence.
