Abstract

Optical tomography based on quantitative phase microscopy is used to determine nondestructively and with high spatial resolution the three‐dimensional (3D) refractive index distributions within optical fiber devices. After obtaining a series of phase images of the fiber as it is rotated around its longitudinal axis at regularly‐spaced angular positions, filtered backprojection is used to reconstruct a 3D map of the refractive index. The 3D refractive index distribution of the join region between two fusion spliced optical fibers is reconstructed with accuracy better than 10^−3^. Microsc. Res. Tech., 2008. © 2007 Wiley‐Liss, Inc.
