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…

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…

Rapid broadband characterization of scattering medium using hyperspectral imaging
People at LKB (and St. Andrews) keep shining light into scattering media. This time, they have developed a cool approach for measuring the multispectral Transmission Matrix (MSTM) of a medium. This knowledge allows to control each spectral component of a light beam when travelling through the medium, which permits to shape, for example, the spectral…
