New paper in Results in Physics about the diffraction of a double polarizer rectangular aperture
Our last paper is published in Results in Physics, entitled Combination of Fourier transform Jones matrix and beam coherence polarization matrix: Application to a double polarizer rectangular aperture.
Here we integrate the Fourier transform Jones (FTJ) matrix approach with the beam coherence- polarization (BCP) matrix, suitable for describing partially coherent and partially polarized light.
We apply the method to a meaningful example: a rectangular aperture with orthogonal polarizers on each half, illuminated with uniform randomly polarized light. We provide experimental validation using a randomly polarized He-Ne laser and a specially fabricated double polarizer mask. Furthermore, by placing a polarizer behind the polarization diffractive optical element, we generate a scalar beam with spatial incoherence across two distinct zones, suggesting the potential use of randomly polarized lasers with binary patterned polarizers to encode arbitrary binary coherence functions.
The work has been done in collaboration with our colleagues Juan Campos and Angel Lizana, from Universitat Autònoma de Barcelona.
