Abstract

We describe and demonstrate an interferometric side-scattering technique for measuring the microstructure geometry of nested antiresonant hollow-core fiber (NANF). Using this technique, we are able to non-invasively measure the diameters of all the thin tubular capillaries in a NANF with sub-micron accuracy.
