Holography and holographic interferometry as a means for nondestructive testing, as well as
metrologic tools in engineering, biology, and other fields, have significant momentum by the …

A comparative study of quantitative phase imaging techniques for refractometry of optical
waveguides is presented. Three techniques were examined: a method based on the …

Batteries are seen as a vital piece for actual carbon‐neutral world needs. However, as they
basically operate through extremely exothermic electrochemical events, special attention …

A digital holographic microscopic chromatography-based approach with considerably
improved accuracy, simplified configuration and performance stability is proposed to …

Accurate knowledge of the internal core distribution of multicore fibres (MCFs) is essential,
given their widespread application, including in fibre splicing, bundle fan-in/fan-out, mode …

Considering the utilizing of geometrical birefringence, we propose a new type of stress-
induced polarization-maintaining fiber (PMF) with a 'leaf-shaped'core—a structure found by …

A theory to recover refractive index profile of the bent graded index (GRIN) optical fibre, in
core region, is proposed. This theory is applied to the bent GRIN optical fibre when it is …

Refractive index profile (RIP) determines the property and effectiveness of optical fibers.
Accurate measurement of the RIP is essential for fiber fabrication, test and calibration. At …

This paper describes a method for optical projection tomography for the 3D in situ
characterization of micrometric plant fibers. The proposed approach is based on digital …

A method to quantitatively measure the refractive index (RI) and the topography of
transparent samples is proposed. Three quantitative phase images at different wavelengths …
