In this work we develop a partially-coherent spirally-polarized imaging system for generating gradual edge detection images. A rotating diffuser is used for producing illumination sources with tunable degree of coherence. Using a 4f configuration, th

The detection of the longitudinal component of a highly focused electromagnetic beam is not a simple task. Although in recent years several methods have been reported in the literature, this measure is still not routinely performed. This paper descri

We explore the detection limits of the Degree of Polarization by capturing Light Fields and introducing a semi-empirical formula to model its behaviour as the mean amount of detected photons in the sensor decreases.

The calculation of the propagation of partially coherent and partially polarized optical beams involves using 4D Fourier Transforms. This poses a major drawback, taking into account memory and computational capabilities of nowadays computers. In this

Under low light conditions, sensor noise perturbs the photodetection distribution. Using light field cameras, we present a biased estimator that reduces sensor noise and is equivalent to the maximum likelihood estimator under high illumination condit
