Slides and abstract of my talk "Interferometric single-pixel imaging with a multicore fiber" made at ISCS23 (Luxembourg, June 12-14, 2023) now available at https://laurentjacques.gitlab.io/event/interferometric-single-pixel-imaging-with-a-multicore-fiber/ and https://laurentjacques.gitlab.io/publication/interferometric-single-pixel-imaging-with-a-multicore-fiber/ All this is based on the work of Olivier Leblanc.

Very happy of this 3-year work on "Interferometric #lensless #imaging: rank-one projections of image frequencies with #speckle illuminations" (https://arxiv.org/abs/2306.12698) carried out by Olivier Leblanc (ICTEAM, UCLouvain, Belgium), in collaboration with Mathias Hofer (Inst. Fresnel, France), Siddharth Sivankutty (U. Lille, France), and Hervé Rigneault (Inst. Fresnel, France).

In this work, we study how lensless imaging with a multicore fiber amounts to probing the spatial frequency content of an image (e.g., a biological sample for potential endoscopic applications).

In particular, by randomly programming the phase of the light emitted by each core (thanks to a spatial light modulator), the sensing model amounts to combining frequencies of the sample image, and this combination is explained by a rank-one projection model of a certain interferometric matrix.

Knowing this model improves our understanding of the model and eases the calibration compared to other speckle imaging approaches.

A #speckle search for the outer companion of KIC 9832227: https://arxiv.org/abs/2304.13729 - " Gemini-N/'Alopeke speckle observations of #KIC9832227, a system originally predicted to become a #RedNova. The diffraction limited observations do not find an outer companion between 11 and 678 AU that could be responsible for the period changes of the system."

Have a look at #speckle and see if they have a relevant connector. Maybe you can get it from the authoring software directly.

Some cross stitch I've done in the past. Haven't picked it up in a while because the last piece I did was symmetrical (The VVitch one) and my OCD made it Very Not Fun. #crossstitch #hobby #crossstitching #thewitch #thevvitch #snowwhite #speckle #tucaandbertie #boldandbrash #spongebob

#Speckle have launched a new tutorials collection giving you options for getting from closed #BIM to #OpenBIM. Go check it out! https://speckle.systems/tutorials/

Today is going to be part reality, part fun. Morning doing my VAT return. Afternoon building a #dynamo script to pull digitised tree data from #laserscan through #speckle into #revit then out to #b3d

Our friends over at #speckle have a brand new viewer rewritten with the 2.9 release. With a brand new viewer, comes a brand new feature: Shadows☂. Go to http://speckle.xyz and try it yourself.
