• Time Fourier domain low coherence interferometry 

    Cerrotta, Santiago; Torga, Jorge Román; Morel, Eneas Nicolás (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 

    Sallese, Marcelo; Torga, Jorge Román; Tabla, Pablo; Morel, Eneas Nicolás (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 ...
