Accuracy and Mechanistic Details of Optical Printing of Single Au and Ag Nanoparticles
(2017-08-30)
Optical printing is a powerful all-optical method that allows the incorporation of colloidal nanoparticles (NPs) onto substrates with nanometric precision. Here, we present a systematic study of the accuracy of optical ...
Room evacuation through two contiguous exits
(Physica A: Statistical Mechanics and its Applications, 2017-05-15)
Current regulations demand that at least two exits should be available for a safe evacuation during a panic situation. Although the "faster is slower" effect is expected to take place near the exits, the evacuation time ...
Fabry Perot detector for low coherence interferometry
(2023-06)
Se proponen dos diseños teóricos de detectores de intensidad para distintas longitudes de onda basados en cavidades Fabry Perot para ser aplicados en la técnica de interferometría de baja coherencia en el dominio de las ...
Scanning optical coherence tomography applied to the characterization of surfaces and coatings
(El Sevier, 2014)
This paper shows the technique of optical coherence tomography in the frequency domain (OCT-FD) to obtain surface topography and tomography of surface coatings. The setup is based on a superluminescent diode centered on ...
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 ...
Extending low-coherence interferometry dynamic range using heterodyne detection
(2020-08)
Low-coherence interferometry (LCI) technique is generating considerable interest in industrial applications where there is a need for larger measurements with high resolution. Conventional Fourier domain systems reach a ...
Feasibility and analysis of a system of two in tandem interferometers for optical coherence tomography
(IEE Explore Digital Library, 2017-12-18)
A signal obtained from a combined system of two interferometers of low coherence in the frequency domain is presented and analyzed. This system allows to expand the range of measurement offered by the conventional optical ...
