Analysis of three-dimensional object reconstruction algorithms based on multi-camera arrays
(2020-08)
In this paper, we present a reliable method for three-dimensional object reconstruction based on multi-camera sensor arrays. Camera arrays are an efficient strategy for high-performance imaging and view interpolation. ...
Fluorescência por absorção de dois fótons em corantes com aplicações biológicas
(Universidade Federal de Minas GeraisUFMG, 2013-03-15)
We use the technique of fluorescence by two photon absorption to study some dyes that are important for applications in biological imaging. Some biological samples are autofluorescent, i.e. they have a high absorption cross ...
Bloch surface waves in photonic crystal fibers
(Medellín - Ciencias - Doctorado en Ciencias - FísicaEscuela de físicaUniversidad Nacional de Colombia - Sede Medellín, 2019-09-13)
An electromagnetic surface wave (ESW) is a wave that travels at the interface between two media, and their fields decay exponentially on both sides of the boundary. ESWs are widely studied due to their potential applications ...
Multi-wavelength emission through self-induced second-order wave-mixing processes from a Nd3+ doped crystalline powder random laser
(2015-09-03)
Random lasers (RLs) based on neodymium ions (Nd3+) doped crystalline powders rely on multiple light scattering to sustain laser oscillation. Although Stokes and anti-Stokes Nd3+ RLs have been demonstrated, the optical gain ...
Silicon isotope separation by two frequency IRMPDSeparación isotópica de Si mediante la DMFIR con dos frecuencias
(Sociedad Espanola de Optica, 2017-08)
InfraRed Multi-Photon Dissociation (IRMPD) is a highly selective laser isotope separation technique. This process consists of a sequential IR photon absorption from the ground vibrational state up to dissociation by a ...
