Exoplanetary
system imaging
Our team developed the THD bench, an optical high contrast imaging bench that is used to test and optimize several devices in the context of direct imaging of exoplanets. We worked on several coronagraphic and wavefront control techniques: four quadrant phase mask (FQPM), multi-FQPM, dual zone phase mask, self-coherent camera. Most of our work is described on the THD bench website.
I am involved in the SPHERE+ project for the VLT and in the PCS
instrument for the
ELT.
Biological
imaging
The objective of my biological
imaging team is to
apply techniques
developed for
high angular imaging
in astronomy to
microscopy. In 2026,
our main goal is to
develop a microscope
that enables the
ex-vivo imaging of
whole clarified rodent
brains (1cm3) with a
1µm3 resolution in
less than
6h. The current
systems as confocal
microscopy a slow
(more than 72h) and
the resolution is not
uniform in the whole
sample. We propose to
first obtain a medium
resolution image
(10µm3) using a
lightsheet
illumination. Then, a
confocal microscope
combined with an
adaptive optics system
provides the imaging
of the regions of
interest with a 1µm3
resolution.(Click on
