Abstract

In this work we describe the application of time domain optical coherence tomography to characterize optical fibers. The system presents the capability to construct cross-sectional images of the fiber; however, as the aim of the work is to establish the refractive indexes profiles boundaries across the sample, the device works as a low coherence interferometer. The equipment resolutions are about 20 Â¿m for axial resolution and 35 Â¿m for transversal resolution, allowing multimode fibers to be investigated with the technique. Results for physical dimensions and refractive indexes are presented and discussed.
