Extending low-coherence interferometry dynamic range using heterodyne detection
(2020-08)
Low-coherence interferometry (LCI) technique is generating considerable interest in industrial applications where there is a need for larger measurements with high resolution. Conventional Fourier domain systems reach a ...
Feasibility and analysis of a system of two in tandem interferometers for optical coherence tomography
(IEE Explore Digital Library, 2017-12-18)
A signal obtained from a combined system of two interferometers of low coherence in the frequency domain is presented and analyzed. This system allows to expand the range of measurement offered by the conventional optical ...
