The real trombone champ, Google’s special treatment, and more: THE WEEKLY RECAP (2022#39)

Lots of funny stories this week. Trombone Champ is blowing it, Jack Dorsey is a maniac, AI keeps spreading over all the aspects of our life, Google manages to be evil again, and people are finally starting to take action against the nonsensical fashion industry. Let's start: The real trombone champ That was quick! People …

Large field-of-view non-invasive imaging through scattering layers using fluctuating random illumination

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 …

Facecrap, Bezosism, and more: THE WEEKLY RECAP (2021#37)

Really packed week, so let's start right away. Enhance! Another year, another amazing contest of scientific photography. I particularly liked the third place, though all the images are really impressive. 2021 PHOTOMICROGRAPHY COMPETITION, on nikonsmallworld Nintendo being Nintendo Honestly, I thought that after 4 years they were not going to add bluetooth support for headphones, …

Single frame wide-field Nanoscopy based on Ghost Imaging via Sparsity Constraints (GISC Nanoscopy)

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 …

Simultaneous multiplane imaging with reverberation multiphoton microscopy

Really nice pre-print by the people at Boston University, leaded by J. Mertz. Love the idea of generating ~infinite focal spots (until you run out of photons) inside a sample, and using a extremely fast single-pixel detector to recover the signal. Very original way to tackle volumetric imaging in bio-imaging! Fundamental workflow of the technique. …

De-scattering with Excitation Patterning (DEEP) Enables Rapid Wide-field Imaging Through Scattering Media

Very interesting stuff from the people at MIT regarding imaging through scattering media. Recently, multiple approaches taking advantage of temporal focusing (TF) increased efficiency inside scattering media when using two-photon microscopy have been published, and this goes a step further. Here, the authors use wide-field structured illumination, in combination with TF, to obtain images with …
