Preliminary study of a heterodyne detection system for optical coherence tomography signals
(2019-10-24)
A heterodyne detection system for optical coherence tomography signalsis presented and characterized. The system allows to expand the range of measurement and overcome the limitations of conventional systems which typically ...
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 ...
