Interferometric system based on swept source-optical coherence tomography scheme applied to the measurement of distances of industrial interest
(2015-12-11)
We used an interferometric technique based on typical optical coherence tomography (OCT)
schemes for measuring distances of industrial interest. The system employed as a light source a tunable erbium-doped fiber laser of ...
Extensión del rango dinámico de la tomografía óptica coherente sensible a la fase
(RAFA - Santa Fé, 2019-10)
La tomografía óptica coherente sensible a la fase (PhS-OCT), también conocida como microscopía de fase (SDPM), es una técnica que se basa en la medición de la fase en la señal de interferencia obtenida por tomografía óptica ...
Large Axial Range Frequency-Domain Optical Low Coherence Interferometry
(2019-01-15)
In this paper, we propose a new experimental setup to extend the measurement range of frequency-domain low coherence interferometry (FD-LCI) from 3 mm to 2 cm. The FD-LCI can be extended to the technique of frequency domain ...
