Arenas, "Spectral sensor resolution measurement improvements by temporal analysis," 2017 XVII Workshop on Information Processing and Control (RPIC), Mar del Plata, 2017, pp. 1-5, doi: 10.23919/RPIC.2017.8214341.978-987-544-754-7http://hdl.handle.net/20.500.12272/4515In 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 such as position, length and vibrations, in the spectral domain with improved resolution by a temporal analysis. In particular, Fourier domain SDI (FD-SDI), is able of measuring absolute cavity lengths with a resolution of 10 μm typically, depending on the bandwidth of the optic source and the spectrometer. Alternatively, TDI allows making displacement measurements within a resolution of λ/10, depending on the laser light wavelength (λ) used.application/pdfenginfo:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by-nc-sa/4.0/Atribución-NoComercial-CompartirIgual 4.0 InternacionalUTNFacultad Regional DeltaOptical interferometrySiliconSpectral analysisDetectorsDiscrete Fourier transformsTime-domain analysisOptical fibersinfo:eu-repo/semantics/conferenceObjectAntonacci, J.Atribución – No Comercial – Compartir Igual (by-nc-sa)
