During my stay in Paris, one of the topics I have been working on is related to the problem of imaging objects hidden by scattering media. While seeing stuff through transparent materials is quite easy, the thing becomes much more complicated when light gets randomly deviated in all directions. This might seem quite a particular …
Earlier this year, I was at Photonics Europe 2022 in Strasbourg. I had a lot of fun with many talks, but there was one topic that really piqued my interest: additive manufacturing. I have always been interested in 3D printing, and I know from experience how useful they can be: printing mechanical pieces in the …

Data fusion concept. From Fig.1 in the manuscript. Do you want a 4D reconstruction? Just take several 2D/3D objects and merge them in a clever way. Some time ago I wrote a short post about using Data Fusion (DF) to perform some kind of Compressive Sensing (CS). We came with that idea when tackling a …
Really cool implementation of Single-pixel Imaging + Compressive Sensing from the people at University of Birmingham. Using hyperspectral data measured with a single-pixel spectrometer + tomographic reconstruction, they show that it is possible to perform Bioluminiscence Imaging. Nice to see that the topics I used to work keep showing super cool results. Single pixel hyperspectral …

Some time ago I started working on some kind of data fusion problem where we have access to several imaging systems working in parallel, each one gathering a different multidimensional dataset with mixed spectral, temporal, and/or spatial resolutions. The idea is to perform 4D imaging at high spectral, temporal, and spatial resolutions using some single-pixel/multi-pixel …

Nice ghost imaging implementation on a chip. Even though the optical part has been quite well-known for a while, I really like the fact that more groups are starting to incorporate FPGA cards in their optical systems (if only they were easier to use!). Seems like a very interesting way of speeding-up the post-processing of …
