Dimensional characterization of large opaque samples and microdeformations by low coherence interferometry
We report on the application of an interferometric system based on the low-coherence interferometry technique to the dimensional characterization of large opaque mechanical parts as well as microdeformations experienced ...
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 ...
Interferometric system based on swept source-optical coherence tomography scheme applied to the measurement of distances of industrial interest
We used an interferometric technique based on typical optical coherence tomography (OCT) schemes for measuring distances of industrial interest. The system employed as a light source a tunable erbium-doped fiber laser of ...
Improved spectral resolution in time-varying interferometry
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 ...
