Experimental analysis of a joint free space cryptosystem
(Elsevier, 2016-08)
In this paper, we analyze a joint free space cryptosystem scheme implemented in an actual laboratory environment. In this encrypting architecture, the object to be encoded and the security key are placed side by side in ...
Using an aliasing operator and a single discrete Fourier transform to down-sample the Fresnel transform
(Optical Society of America, 2012)
Phase recovery by using optical fiber dispersion
(Optical Society Of America, 2014-02)
We propose a simple and fast procedure to retrieve the phase profile of arbitrary light pulses. It combines a first experimental stage, followed by a one-step numerical stage. To this end, it is necessary to perform a ...

Designing Fresnel microlenses for focusing astigmatic multi-Gaussian beams by using fractional order Fourier transforms
(Institute of Physics Publishing, 2011)
According to a scalar theory of diffraction, light propagation can be expressed by two-dimensional fractional order Fourier transforms. Since the fractional Fourier transform of a chirp function is a Dirac distribution, ...
