Paper Abstract

The tomographic refractive index imaging technique by digital holographic microscopy with sample rotation is presented. First, transmission phase images are numerically reconstructed from holograms acquired at regularly-spaced angular positions for the rotating sample. Then, the three-dimensional refractive index spatial distribution is reconstructed by filtered back-projection algorithm. Last, the experiments are carried out and the three-dimensional refractive index distribution of single-mode and single-mode polarization maintaining optical fibers is accurately reconstructed.
