Mueller Matrix Polarimetry

Welcome to the website of Oriol Arteaga. Here you will mostly hear about my research activities which mainly focus in polarimetry, ellipsometry or, more in general, in light-matter interactions. You can contact me at oarteaga(AT)ub.edu and at www.ub.edu/plat

Listing some updates

Posted on by loiro

Several months have passed without updates on the website, so it is time to at least post a summary of the latest activities.

  • In November 2025, I visited China again. I stayed at Huaqiao University, visited former PhD students of the group at Jimei University, attended the ERA & MMI 2025 conference in Hangzhou, and also spent a few days in Shanghai, where I visited the lab of my old friend and collaborator c Prof. Xiaoyan Cui.
  • In Jan 2026, I attended Photonics West conference in San Francisco. It was my first time at this huge event, with its impressive exhibition. I am not a big fan of this type of conferences, but it was worth seeing at least once. I mainly participated in the Polarized Light and Optical Angular Momentum for Biomedical Diagnostics 2026 conference.
  • Check our new ONE PAGER for the full-Stokes polarization camera: onepager POLVISON. Over the past months, we have refined the polarimeter, making a more robust calibration and offering higher resolution images. To my knowledge, there is currently no simple, affordable and instantaneous full-Stokes imaging system on the market, and our system aims to fill this gap.
  • In Dec 2025. Prof. Razvigor Ossikovski visited the group as part of our long-lasting collaboration. Our lastest work can be found here in already online: Completing Experimental Non-Depolarizing Mueller Matrix with Both a Row and a Column Missing,Razvigor Ossikovski and Oriol Arteaga DOI: 10.1364/JOSAA.588312 Received 23 Dec 2025; Accepted 29 Jan 2026; Posted 30 Jan 2026  View: PDF
  • In the last months the group have published several papers (full list on my Google scholar profile). Topics are diverce, to cite a few from a retropective paper on Pi phases in optics, a work that combines spatial frequency domain imaging with polarimetry,  and even a collaboration work on chiral materials that leads into Science journal.
  • Next week I will be attending the 13th Workshop on Spectroscopic Ellipsometry in Italy where I will present a tutorial session on spectroscopic ellipsometry and also a talk about showing some of the latest improvement on my snapshot polarimetry/ellipsometry (need to update the website with newest results).

NOTE. I receive several requests for PhD and postdoctoral opportunities (I assume some request come because people find my group through this website). Unfortunately, we usually have no open vacancies, as our projects rarely have sufficient funding to cover personnel costs. However, interested candidates may still join the group through competitive calls (Spanish predoctoral and postdoctoral programs, as well as international calls such as the China CSC program).
