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 ...
Simultaneous measurement of deformation and thickness change in polymer films
(2006-08-14)
We present experimental results in deformation measurement and thickness change in polymer films employing Fourier domain interferometry. The set-up is a Michelson configuration in which interference signal betweeen light ...
Simple method for thickness measurement in opaque samples with a Michelson-Sagnac interferometer
(2008-04-24)
We present in this work a method to measure thicknesses of opaque samples. The technique combines the use of low coherence interferometry with a Michelson-Sagnac configuration. This ring set-up let us to measure both faces ...
