摘要

We report the experimental results of structural parameters measurement of the polarization-maintaining fiber (PMF) by the use of digital holographic microtomography. First, digital holography (DH) in microscopy configuration is used to record complex transmitted fields under various angles of incidence, and then the Fourier diffraction tomography algorithm is applied to reconstruct the 3-D refractive index (RI) distribution of the PMF. According to the 3-D map of RI, we can further get geometric parameters of the PMF by the related edge detection algorithm of image processing. The experimental results show that, the diffraction tomography algorithm is superior to the reconstruction algorithm based on Fourier slice theorem in terms of exhibiting reasonable RI distribution and respecting the dimensions of the PMF. It provides a new way for the non-destructive micromeasurement of the PMF. (C) 2015 Elsevier Inc. All rights reserved.
