New paper in Scientific Reports about generating customized depolarizated spatial light patterns
In our recent paper in Scientific Reports entitled Customized depolarization spatial patterns with dynamic retardance functions we demonstrate a proof-of-concept of a dynamical time-dependent pixelated retarder used to emulate a controlled spatially variant depolarizing sample.
We apply an imaging Mueller polarimetric system based on a polarization camera to verify the effective depolarization effect, and the effective depolarizance results are fully described within a simple graphical approach and standard Mueller matrix decomposition methods. The technique is illustrated by means of three practical cases, including exotic structures as a spirally shaped depolarization pattern.
The work has been done in collaboration with our colleagues Angel Lizana and Juan Campos, from MIP Optilab Laboratory at the Department of Physics of Universitat Autònoma de Barcelona, in the frame of our common research project devoted to the development of advanced polarimetric systems.
This work is also part of the PhD Thesis of David Marco.
