Modelling Fourier filtering wavefront sensors for PSD-based methods: the AOPERA tool
Romain Fétick, Vincent Chambouleyron, Lisa-Marie Mazzolo +6
Compensation of the atmospheric turbulence thanks to adaptive optics (AO) has now become commonly used for VLT or ELT class telescopes in order to retrieve a resolution close to th…
Super-resolution wavefront reconstruction in adaptive-optics with pyramid sensors
Carlos M. Correia, Charlotte Z. Bond, João Aveiro +3
Super-resolution (SR) refers to a combination of optical design and signal processing techniques jointly employed to obtain reconstructed wave-fronts at a higher-resolution from mu…
The GPU-based High-order adaptive OpticS Testbench
Byron Engler, Markus Kasper, Serban Leveratto +12
The GPU-based High-order adaptive OpticS Testbench (GHOST) at the European Southern Observatory (ESO) is a new 2-stage extreme adaptive optics (XAO) testbench at ESO. The GHOST is…
The Bi-O-edge wavefront sensor: How Foucault-knife-edge variants can boost eXtreme Adaptive Optics
C. Vérinaud, C. T. Heritier, M. Kasper +1
Direct detection of exoplanets around nearby stars requires advanced Adaptive Optics (AO) systems. High order systems are needed to reach high Strehl Ratio (SR) in near infrared an…
The ESO's Extremely Large Telescope Working Groups
Paolo Padovani, Michele Cirasuolo, Remco van der Burg +82
Since 2005 ESO has been working with its community and industry to develop an extremely large optical/infrared telescope. ESO's Extremely Large Telescope, or ELT for short, is a re…
Redundant Apodized Pupils (RAP) for high-contrast imagers robust to segmentation-due aberrations and island effects
Lucie Leboulleux, Alexis Carlotti, Mamadou N'Diaye +6
The imaging and characterization of a larger range of exoplanets, down to young Jupiters and exo-Earths will require accessing very high contrasts at small angular separations with…
