Simultaneous source and attenuation reconstruction in spect using ballistic and single scattering data
(2015)
In medical single-photon emission computed tomography (SPECT) imaging, we seek to simultaneously obtain the internal radioactive sources and the attenuation map using not only ballistic measurements but also first-order ...

Implementation of a bright frequency correlated photon pairs source based on a PPKTP crystal
(Universidad de los AndesFísicaFacultad de CienciasDepartamento de Física, 2021)
The implementation of a bright frequency correlated photon pairs source based on a PPKTP requires two principal parts: the process of Spontaneous Parametric Down-Conversion SPDC taking into account the quasi-phase-matching ...
Modeling transition diffusive - non diffusive transport in a turbid media and application to time-resolved reflectance
(Elsevier, 2013-02)
In this work a generalized solution for the photon density is proposed and applied to two types of experiments in turbid media carried out in the last years. Both involve small typical distances, where it is known that the ...
Estudo da correlação de fótons e controle óptico a partir do fenômeno da transparência eletromagneticamente induzida em cavidades para um átomo de três níveis
(Universidade Federal de São CarlosUFSCarCâmpus SorocabaFísica - FL-So, 2022-04-29)
The ability to produce and control single photons is one of the outstanding goals of quantum optics to pave the way towards the implementation of quantum devices. In this work, we present a theoretical study on the phenomenon ...
