Focal Plane Wavefront Sensing on SUBARU/SCExAO
Sebastien Vievard, Steven P. Bos, Frederic Cassaing +20
Focal plane wavefront sensing is an elegant solution for wavefront sensing since near-focal images of any source taken by a detector show distortions in the presence of aberrations…
FIRST, a Pupil-Remapping Fiber Interferometer at the Subaru Telescope: on-sky results
Sébastien Vievard, Elsa Huby, Sylvestre Lacour +13
FIRST, the Fibered Imager foR a Single Telescope, is a spectro-imager using single-mode fibers for pupil remapping, allowing measurements beyond the telescope diffraction limit. In…
The Automated Data Extraction, Processing, and Tracking System for CHARIS
Taylor L. Tobin, Jeffery Chilcote, Timothy Brandt +4
CHARIS is an IFS designed for imaging and spectroscopy of disks and sub-stellar companions. To improve ease of use and efficiency of science production, we present progress on a fu…
KalAO the swift adaptive optics imager on 1.2m Euler Swiss telescope in La Silla, Chile
Janis Hagelberg, Nathanaël Restori, François Wildi +6
KalAO is a natural guide star adaptive optics (AO) imager to be installed on the second Nasmyth focus of the 1.2m Euler Swiss telescope in La Silla, Chile. The initial design of th…
An Atmospheric Dispersion Corrector Design with Milliarcsecond-Level Precision from 1 to 4 microns for High Dispersion Coronagraphy
Jason J. Wang, J. Kent Wallace, Nemanja Jovanovic +3
Differential atmospheric refraction (DAR) limits the amount of light that can be coupled into a single mode fiber and provides additional complications for any fiber tracking syste…
On-sky performance and recent results from the Subaru coronagraphic extreme adaptive optics system
Thayne Currie, Olivier Guyon, Julien Lozi +10
We describe the current on-sky performance of the Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument on the Subaru telescope on Maunakea, Hawaii. SCExAO is continuing…
