MKID, an energy sensitive superconducting detector for the next generation of XAO
Aurelie Magniez, Lisa Bardou, Tim Morris +1
Selected for the next generation of adaptive optics (AO) systems, the pyramid wavefront sensor (PWFS) is recognised for its closed AO loop performance. As new technologies are emer…
MOSAIC: the high-multiplex and multi-IFU spectrograph for the ELT
Rubén Sánchez-Janssen, Francois Hammer, Simon Morris +40
MOSAIC is the planned multi-object spectrograph for the 39m Extremely Large Telescope (ELT). Conceived as a multi-purpose instrument, it offers both high multiplex and multi-IFU ca…
Wavefront prediction using artificial neural networks for open-loop Adaptive Optics
Xuewen Liu, Tim Morris, Chris Saunter +3
Latency in the control loop of adaptive optics (AO) systems can severely limit performance. Under the frozen flow hypothesis linear predictive control techniques can overcome this,…
Limitations imposed by optical turbulence profile structure and evolution on tomographic reconstruction for the ELT
O. J. D. Farley, J. Osborn, T. Morris +4
The performance of tomographic adaptive optics systems is intrinsically linked to the vertical profile of optical turbulence. Firstly, a sufficient number of discrete turbulent lay…
The adaptive optics modes for HARMONI: from Classical to Laser Assisted Tomographic AO
B. Neichel, T. Fusco, J. -F. Sauvage +25
HARMONI is a visible and NIR integral field spectrograph, providing the E-ELT's core spectroscopic capability at first light. HARMONI will work at the diffraction limit of the E-EL…
