The MICADO first light imager for the ELT: an overview of the RAM analysis and consequent design and maintenance strategy
Federico Biondi, Yann Clénet, Patrick Caillier +7
MICADO is a cryogenic near infrared Multi-AO Imaging Camera and Spectrometer developed for the first light operations at the ELT. It will operate in a "Standalone" configuration wi…
The MICADO first-light imager for the ELT: first steps of the SCAO system MAIT
Yann Clénet, Eric Gendron, Fabrice Vidal +39
MICADO is the ELT first light instrument, an imager working at the diffraction limit of the telescope thanks to two adaptive optics (AO) modes: a single conjugate one (SCAO), avail…
CASSTOR: a scientific and technology nanosatellite demonstrator for UV spectropolarimetry
Coralie Neiner, Vincent Lapeyrere, Eitan Pechevis +18
In the context of the development of several space mission projects for UV spectropolarimetry at high resolution and over a wide UV wavelength range, such as Arago, Polstar, and Po…
The MICADO first light imager for the ELT: off-axis performance of PSF reconstruction
Matteo Simioni, Daniel Jodlbauer, Carmelo Arcidiacono +14
The highest scientific return, for adaptive optics (AO) observations, is achieved with a reliable reconstruction of the PSF. This is especially true for MICADO@ELT. In this present…
Astrometric and photometric accuracies in high contrast imaging: The SPHERE speckle calibration tool (SpeCal)
R. Galicher, A. Boccaletti, D. Mesa +21
The consortium of the Spectro-Polarimetric High-contrast Exoplanet REsearch installed at the Very Large Telescope (SPHERE/VLT) has been operating its guaranteed observation time (2…
On-sky demonstration of matched filters for wavefront measurements using ELT-scale elongated laser guide stars
A. G. Basden, L. Bardou, D. Bonaccini Calia +18
The performance of adaptive optics systems is partially dependant on the algorithms used within the real-time control system to compute wavefront slope measurements. We demonstrate…
MICADO: first light imager for the E-ELT
R. Davies, J. Schubert, M. Hartl +80
MICADO will equip the E-ELT with a first light capability for diffraction limited imaging at near-infrared wavelengths. The instrument's observing modes focus on various flavours o…
Experience with wavefront sensor and deformable mirror interfaces for wide-field adaptive optics systems
A. G. Basden, D. Atkinson, N. A. Bharmal +56
Recent advances in adaptive optics (AO) have led to the implementation of wide field-of-view AO systems. A number of wide-field AO systems are also planned for the forthcoming Extr…
An aperture masking mode for the MICADO instrument
S. Lacour, P. Baudoz, E. Gendron +8
MICADO is a near-IR camera for the Europea ELT, featuring an extended field (75" diameter) for imaging, and also spectrographic and high contrast imaging capabilities. It has been…
Current results of the PERSEE testbench: the cophasing control and the polychromatic null rate
Julien Lozi, Frederic Cassaing, Jean-Michel Le Duigou +11
Stabilizing a nulling interferometer at a nanometric level is the key issue to obtain deep null depths. The PERSEE breadboard has been designed to study and optimize the operation…
PERSEE: Experimental results on the cophased nulling bench
Julien Lozi, Frédéric Cassaing, Jean-Michel Le Duigou +15
Nulling interferometry is still a promising method to characterize spectra of exoplanets. One of the main issues is to cophase at a nanometric level each arm despite satellite dist…
