Optimized generation of spatial qudits by using a pure phase spatial light modulator
(IOP Publishing, 2014-11)
We present a method for preparing arbitrary pure states of spatial qudits, namely, D-dimensional ($D\geqslant 2$) quantum systems carrying information in the transverse momentum and position of single photons. For this ...
Assessment of multifractal analysis in dynamic laser speckle signals using a spatial light modulator
(Optical Society of America, 2019-02)
We assess and discuss several technical aspects of the multifractal statistical analysis applied to time series of dynamic speckle intensity signals. Due to the complexity of this goal, we implemented an optical setup that ...
The minimum Euclidean distance principle applied to improve the modulation diffraction efficiency in digitally controlled spatial light modulators
(Optical Society Of America, 2010)
Digital addressing of the electrical signal in spatial light modulators, as it is the case in present liquid crystal on silicon (LCoS) displays, may lead to temporal phase fluctuations in the optical beam. In diffractive ...
Least squares method for liquid crystal display characterization
(OSA - The Optical Society, 2017-02)
This paper presents a method for liquid crystal display characterization. It assumes a liquid crystal display can be considered as a polarization-changing device described by a Jones matrix plus a global phase. The Jones ...
Preparing arbitrary pure states of spatial qudits with a single phase-only spatial light modulator
(Optical Society Of America, 2013)
Spatial qudits are D-dimensional (≥2D≥2) quantum systems carrying information encoded in the discretized transverse momentum and position of single photons. We present a proof-of-principle demonstration of a method for ...
Measurement of phase and amplitude modulations in Sb-Based Films
(2009-11-23)
In this work we studied the changes of the optical constants of films in the binary system Sb2O3-Sb2S3 induced by light in the VIS-UV. The measurements were performed before and after homogeneous irradiation of the films ...
