Abstract

An optical fiber parameter measurement system was constructed based on digital holographic microlayer technology, including an optimized optical path system and a software demodulation system. A single optimal hologram at each angle within 180° view was obtained using a sample rotation device to extract the phase distribution of the sample, which was reconstructed and optimized, and then the refractive index distribution inside the optical fiber was reconstructed by a laminar analysis algorithm. The experimental results show that the reconstruction optimization method used in this paper can measure the refractive index inside the optical fiber simply, quickly and accurately.
