Demonstration of a photonic lantern low order wavefront sensor using an adaptive optics testbed
Mark K. Corrigan, Timothy J. Morris, Robert J. Harris +1
We demonstrate the use of an optimized 5 core photonic lantern (PL) to simultaneously measure tip/tilt errors at the telescope focal plane, while also providing the input to an ins…
Representative optical turbulence profiles for ESO Paranal by hierarchical clustering
O. J. D. Farley, J. Osborn, T. Morris +5
Knowledge of the optical turbulence profile is important in adaptive optics (AO) systems, particularly tomographic AO systems such as those to be employed by the next generation of…
Optimizing astrophotonic spatial reformatters using simulated on-sky performance
Theodoros Anagnos, Robert J. Harris, Mark K. Corrigan +7
One of the most useful techniques in astronomical instrumentation is image slicing. It enables a spectrograph to have a more compact angular slit, whilst retaining throughput and i…
The ELT-MOS (MOSAIC): towards the construction phase
Simon Morris, François Hammer, Pascal Jagourel +50
When combined with the huge collecting area of the ELT, MOSAIC will be the most effective and flexible Multi-Object Spectrograph (MOS) facility in the world, having both a high mul…
First light with HiPERCAM on the GTC
Vikram Dhillon, Simon Dixon, Trevor Gamble +20
HiPERCAM is a quintuple-beam imager that saw first light on the 4.2m William Herschel Telescope (WHT) in October 2017 and on the 10.4m Gran Telescopio Canarias (GTC) in February 20…
Opto-mechanical designs for the HARMONI Adaptive Optics systems
Kjetil Dohlen, Timothy Morris, Javier Piqueras Lopez +14
HARMONI is a visible and near-infrared integral field spectrograph equipped with two complementary adaptive optics systems, fully integrated within the instrument. A Single Conjuga…
