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 ...
Improved spectral resolution in time-varying interferometry
(2018-11)
In this work, we present a procedure that allows increasing the resolution of dynamic length measurements made by spectral interferometry. The proposed scheme leads to obtaining a compact photonic instrument with the ability ...
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 ...
Application of a long-rangesweptsource optical coherence tomography-based scheme for dimensional characterization of multilayer transparent objects
(2017-08-18)
This work presents the use of a recently develop edinter ferometric system based on the swept source optical coherence tomography (SS-OCT) technique, which allows the characterization of transparent and semitransparent ...
Spectral sensor resolution measurement improvements by temporal analysis
(IEEE Xplore, 2017-12-18)
In this work we present time domain interferometry (TDI) and spectral domain interferometry (SDI) techniques applied to a fiber optic Fizeau interferometer sensor. This class of sensor is capable of measuring parameters ...
