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 …

This just got posted on the arXiv, and has some interesting ideas inside. Using a ground glass diffuser before a pixelated detector, and after a calibrating procedure where you measure the associated speckle patterns when scanning the sample plane, a single shot of the fluorescence signal speckle pattern can be used to retrieve high spatial …
New single-pixel camera design, but this time using multicore fibers (MCF) and a photonic lantern instead of a spatial light modulator. Cool! The fundamental idea is to excite one of the cores of a MCF. Then, light propagates through the fiber, which has a photonic lantern at the tip that generates a random-like light pattern at its tip. Exciting different cores …

This week we have a lot of interesting stuff: Observing the cell in its native state: Imaging subcellular dynamics in multicellular organisms Adaptive Optics + Light Sheet Microscopy to see living cells inside the body of a Zebra fish (the favorite fish of biologists!). Really impressive images overcoming scattering caused by tissue. You can read …
