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
We can now provide a full-Stokes add-on compatible with cameras using the color polarization sensors Sony IMX250MYR IMX264MYR and IMX253MYR. The system is based on a customized dispersive retarder (described here and patented) this simple accessory features a 3D-printed mount that screws directly onto the camera window, adding no bulk. The dispersive retarder can be…
I recently participated in this publication led by Prof. Richard Robinson’s group (Cornell University) to demonstrate a new pathway for nonreciprocal optics. Instead of relying on complex metamaterials or strong magnetic fields, this work shows how semiconductor nanoclusters can absorb and emit polarized light differently from the front and back via chiral-linear optical interference. https://www.nature.com/articles/s41563-026-02660-0
I did my first paper on Mueller matrix microscopy in 2024. Over the years, we have been working more on the technique (our latest implementation this year). What used to be a complex method taking minutes to acquire and process a single measurement has now been transformed into a very small instrument capable of a…
Last week, I attended the 13th Workshop on Spectroscopic Ellipsometry. I did two presentations (one invited tutorial and one contributed talk). As I have received some email requests to share them, I am sharing them here too. Click on the images to download them. The snapshot presentation contained many videos that I cannot share…
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…
We introduce a novel application of our patented Polvision technology, engineered specifically for advanced dermatological assessment. The new Polvision Dermatoscope integrates our state-of-the-art, real-time full-Stokes polarimetric camera with a custom ring LED illumination system that uses circularly polarized light. This unique configuration allows the system to non-invasively capture a complete polarization dataset from the skin,…
In September 2025, several new members joined the group: Miguel Ares has joined as technical staff under the POLVISION project. He is working on further developing applications and software for our patentend full-Stokes polarization camera. Shuang Chen is a new PhD student from Huaqiao University (Xiamen, China). During his Master’s studies, he carried out excellent…
In the last years, we have had some proof-of-concept or “product” projects to develop cutting-edge polarization imaging and measurement solutions. We are currently seeking partners interested in licensing our technologies. While our primary goal is to collaborate with companies for technology transfer, we very much welcome inquiries from end-users who may benefit directly from our…
I just came across this animation I created nearly 20 years ago (originally in Flash, now converted to video). It’s a bit off-topic, but interestingly, 2005 also marked the 100th anniversary of special relativity.
Our Full-Stokes Polarization Camera technology introduces a new approach to capturing the complete polarization state of light in real-time, including the often-overlooked circular polarization. To the best of our knowledge, this is the smallest and simplest fully operational Full-Stokes camera developed to date. Key Technical Features Complete Stokes Vector Measurement Measure all four Stokes parameters—total…
