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
It is time to welcome 2015. This New Year should be specially interesting for us since it is the International Year of Light and Light-based Technologies. The International Year of Light is a global initiative adopted by the United Nations to raise awareness of how optical technologies promote sustainable development and provide solutions to worldwide challenges in…
In the last few months a good part of my research has been about Mueller matrix microscopy. We have developed a new MM microscope that uses a dual rotating compensator setup and digital demodulation. The spatial resolution and measurement quality is really good. See related publications here and here. This week we have published a…
For some reason I cannot fully understand, certain types of serial decompositions of Mueller matrices became quite popular among experimentalists. I am talking about the polar decomposition and the Lu-Chipman decompositions. These matrix decompositions allow to decompose a matrix in a series of a retarder, a diattenuator and, eventually, also a depolarizer. Of course matrix…
I took these two pictures last week in the lab. Too amazing for not sharing. (click on the image to enlarge) These are three Cetonia Aurata beetles showing different cuticle colors. Can you anticipate how their Mueller matrix looks like?
During 2014-2015 I will be working on a European Marie Curie IIF project, titled Polarimetric characterization of natural and artificial chiral anisotropic media (Nanochirality) at University of Barcelona.
Not many updates lately! I hope this semester I will manage to keep the website more up-to-date. I also want to add a section with some new scientific content in the form of a tutorial, let’s see if I find the time. For the moment today I have updated the publication list in the lazy…
Hinds Intruments is selling the new 150XT Mueller Polarimeter. This instrument was developed in collaboration with New York University using the 4 Photoelastic Modulator (PEM) technology we pioneered. To my knowledge this is the first commercial full Mueller matrix polarimeter with research-grade specifications ever made available . The key element here is the sensitivity. The instrument was…
After more than two years in New York University this month I have started to work again in Universitat de Barcelona. This was possible because some time ago I got a Beatriu de Pinos Fellowship. These are grants to encourage the recruitment of research personnel in the Catalan public sector, be they in universities, research centers or hospital foundations,…
Recently I have been working on how Mueller matrices handle reciprocal and nonreciprocal optical effects. Mueller matrices are truly informativative about reciprocity, but one needs to know how the information is “stored”. A series of two papers are going to be published in Optics Letters about the topic. For the moment they can be accessed…
First message of 2013! Happy New Year to any eventual visitor. Some quick updates to start the year: I have updated the Publications section using an embedded PDF file. I hope this way it is easier to keep it updated! I have recently known that my Phd Thesis [available here] has won the 2nd prize…
