New paper in OLT with a new polarization grating based single shot polarimeter


OLTWe developed a quantitative analysis of the performance of a complete snapshot polarimeter based on a polarization diffraction grating (PDGr). The work has been published in the paper entitled Quantitative performance of a polarization diffraction grating polarimeter encoded onto two liquid-crystal-on-silicon displays, published at the journal Optics & Laser technology.

The PDGr is generated in a common path polarization interferometer with a Z optical architecture that uses two liquid-crystal on silicon (LCoS) displays. The programmable PDGr is capable to act as a simultaneous polarization state generator (PSG), yielding diffraction orders with different states of polarization. The same system is also shown to operate as a polarization state analyzer (PSA), therefore useful for the realization of a snapshot polarimeter. We analyze its performance using quantitative metrics such as the conditional number.

This work has been developed in collaboration with our friends at the Departamento de Ciencias Físicas, Universidad de la Frontera (Chile) and our friends at Departamento de Física de la Universitat Autònoma de Barcelona. And it will part of the PhD Thesis of Aarón Cofré.
