Martínez Matos, Óscar ; Rodrigo Martín-Romo, José Augusto ; Alieva, Tatiana Krasheninnikova ; Cámara, Alejandro ; Cheben, Pavel ; Calvo Padilla, María Luisa | The Optical Society Of America | 2011-03-28In this work, we propose a robust and versatile approach for the characterization of the complex field amplitude of holographically generated coherent-scalar paraxial beams. For this purpose we apply an iterative algorithm that allows recovering[...]texto impreso
Cámara, Alejandro ; Rodrigo Martín-Romo, José Augusto ; Alieva, Tatiana Krasheninnikova | The Optical Society Of America | 2013-06-03Partially coherent light provides attractive benefits in imaging, beam shaping, free-space communications, random medium monitoring, among other applications. However, the experimental characterization of the spatial coherence is a difficult pro[...]texto impreso
Cámara, Alejandro ; Alieva, Tatiana Krasheninnikova ; Rodrigo Martín-Romo, José Augusto ; Calvo Padilla, María Luisa | Society of Photo-Optical Instrumentation Engineers (SPIE) | 2011The application of partially coherent optical beams for imaging, free space communication, random medium analysis requires controlling its mutual intensity. This task can be done using the phase-space tomography method consisting on the reconstr[...]texto impreso
Cámara, Alejandro ; Alieva, Tatiana Krasheninnikova ; Rodrigo Martín-Romo, José Augusto ; Calvo Padilla, María Luisa | Optical Society of America | 2009-06We propose a simple approach for the phase space tomography reconstruction of the Wigner distribution of paraxial optical beams separable in Cartesian coordinates. It is based on the measurements of the antisymmetric fractional Fourier transform[...]texto impreso
Cámara, Alejandro ; Alieva, Tatiana Krasheninnikova ; Rodrigo Martín-Romo, José Augusto ; Calvo Padilla, María Luisa | The Optical Society Of America | 2011-07-11We show the adaptation of a multifunctional optical system consisting of two spatial light modulators for the optimal measurement of the Radon-Wigner transform of one-dimensional signals. The proposed Radon-Wigner display allows reconstructing t[...]texto impreso
Alieva, Tatiana Krasheninnikova ; Cámara, Alejandro ; Rodrigo Martín-Romo, José Augusto | Society of Photo-optical Instrumentation Engineers | 2015-03-13Partially coherent light provides attractive benefits for different applications in microscopy, astronomy, telecommunications, optical lithography, etc. However, design and generation of partially coherent beams with desirable properties is chal[...]texto impreso
Cámara, Alejandro ; Alieva, Tatiana Krasheninnikova ; Rodrigo Martín-Romo, José Augusto ; Calvo Padilla, María Luisa | The Electromagnetics Academy | 2010The numerical demonstration of the phase-space tomographic reconstruction method of non-separable beams is presented in this contribution. The Wigner distribution of a Laguerre-Gaussian beam is recovered from numerically simulated intensity meas[...]
