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 ... -
Time Fourier domain low coherence interferometry
(2022-04)We presented a new system that combine Time Domain and Fourier Domain Low Coherence Interferometry. Moving one interferometer arm the Fourier Transform can be detected in the photodiode. Maths and experimental results are shown. -
Topografía de superficies obtenida por interferometría de baja coherencia de alta resolución espacial
(2016)La tomografía óptica coherente (OCT por sus siglas en inglés) es una técnica óptica no destructiva, que utiliza una fuente de luz de gran ancho espectral que se enfoca sobre un punto de la muestra para determinar la distancia ... -
Transparent glass slab thickness measurement by binary-spot focus signal
(2019-12-12)Focus error systems based on the astigmatic principle relying on four quadrant photo detectors as the signal generation element have widely been used in many different applications. Nevertheless, its working principle ... -
