High CONtrast Imaging & Spectroscopy
march 9th 2012, ESO Chile (Vitacura)
HConIS, first edition
A one-day workshop focused on High
Imaging & Spectroscopy
took place on friday, March 9th 2012.
the OPS-II Session 4 dedicated to new
facilities such as SPHERE, GPI, HiCIAO, etc. People interested in high
concepts, techniques/results and data processing methods were
to sign up for it spend
day in Santiago. We expected
participation from the OPS-II attendants but
others were welcome in particular students, postdocs and engineers
Chile. This mini workshop aimed at filling up the gap in 2012
-waiting from the next
the Spirit of Lyot conference
2013?)- to bring "techno"
and/or "science" oriented people together in the constantly evolving
high-contrast, direct imaging & spectroscopy.
Interested persons should register or contact Julien Girard (me) or Dimitri Mawet and expect the detailed program to be published here. Since it will take also take place at ESO/Vitacura, the maximum capacity will be ~100 persons but we are limited to ~15 oral presentations.
imaging/spectroscopy is on the verge of a technical and
scientific revolution, thanks to the coming of extreme-adaptive optics
facilities at major observatories (SPHERE at the VLT, GPI at Gemini,
Palomar, HiCIAO at Subaru). ExAO will provide excellent image quality
to 8-m class telescope, which will allow the use of new-generation
coronagraphic systems. The baseline coronagraphs for these systems are
representative of the four big families of coronagraphs: image-plane
acting on either amplitude or phase, and pupil-plane devices acting
either amplitude or phase, or a clever mix of all the above. At the
observing strategies, and associated internal calibration and data
techniques, have dramatically improved to allow for a better
subtraction of the
residual systematics affecting high contrast images (speckles), and
to the presence of slowly-varying optical aberrations within the

HCOnIS 2012 featured
20-to-30 min video recorded talks
(see below) and many nice - but not recorded - discussions.
No limitations in Posters, most posters from OPS-II can stay put and HConIS poster can be installed on friday morning.
There were approximately 70 participants.
Lunch, coffee and cheese breaks were kindly offered by the ESO Chile Office for Science.
