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 ...
Long-range frequency domain low-coherence interferometry detector for industrial applications
(2023-01)
A low-cost long-range frequency domain low-coherence interferometry (LCI) detector is presented: time Fourier domain LCI (TFD-LCI). Combining ideas of time domain and frequency domain techniques, the TFD-LCI detects the ...

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 ...
