Journal ArticleDOI
Faraday current sensor with temperature monitoring
TL;DR: A novel optical current sensor based on the Faraday effect that incorporates a temperature monitoring system that Measurement of the plate retardation permits compensation for the temperature dependence of the Verdet constant.
Journal ArticleDOI
Generalized phase-shifting algorithms: error analysis and minimization of noise propagation: erratum.
TL;DR: A new method for generating general phase-shifting algorithms with arbitrarily spaced phase steps is presented and the conditions for which the phase-retrieval error due to phase-shift miscalibration can be minimized are studied.
Journal ArticleDOI
Generation of phase-shifting algorithms with N arbitrarily spaced phase-steps.
TL;DR: This work presents a systematic algebraic approach for generating general PS algorithms with N arbitrarily spaced phase-steps, which present advantages (e.g., the PS error can be avoided) over known algorithms that assume equally spacedphase-steps.
Journal ArticleDOI
Polymer-dispersed liquid-crystal voltage sensor.
Elizabeth Scherschener,César D. Perciante,Enrique A. Dalchiele,Erna Frins,Matthias Korn,José A. Ferrari +5 more
TL;DR: A novel electric-field and voltage sensor based on the electro-optical properties of polymer-dispersed liquid-crystals to achieve linearization of the PDLC response and to measure transmittance changes independently of the light-intensity level variations.
Journal ArticleDOI
Multiple phase-shifted interferograms obtained from a single interferogram with linear carrier
José A. Ferrari,Erna Frins +1 more
TL;DR: In this paper, the authors proposed a new method for phase retrieval in an interferogram with a spatial linear carrier, which does not require sophisticated data-processing and is computationally efficient.
