Si terrà a ROMA dal 21 al 24 Aprile il prossimo Workshop nazionale del laboratorio di ottica adattiva ADONI dove la comunità italiana si incontrerà per presentare e discutere le attività scientifiche e tecniche relative a questa disciplina in ambito INAF ed internazionale.
Introducing a new generation adaptive optics simulation framework: from PASSATA to SPECULA
Fabio Rossi, Alfio Puglisi, Guido Agapito
Abstract
Numerical end-to-end simulation in adaptive optics (AO) is a key tool in the development of complex systems, from the initial design to the commissioning phase. Based on our previous experience with PASSATA, we decided to develop a new AO simulation framework in the Python language, naming it short for: scalable parallel execution of computations upscaling large adaptive optics simulations (SPECULA). Following an object-oriented approach, the physical entities are modeled as processing objects connected to each other to exchange data objects … leggi di più

SHARK-NIR: il sito web!
Ciao a tutti, in abito semplice e con molta voglia di migliorarsi e crescere ecco a voi il sito web di SHARK-NIR: https://sites.google.com/inaf.it/shark-nir/home
Il progetto, il cui cuore pulsante e gli sporchi cacciavitari impegnati nella fase di integrazione hanno sede nei laboratori dell’Osservatorio di Padova, e’ la futura camera coronografica nel vicino infrarosso per il Large Binocular Telescope in Arizona.

Wavefront sensing in the VLT/ELT era + AO workshop week
Due to the COVID-19 situation, the following AO events were momentarily suspended in Europe:
- the AO workshop week in March/June 2020 in Porto
- the Wavefront sensing in the VLT/ELT era in October 2020 in Nice
The health conditions have been evolving favourably for the past few weeks (in Europe). Based on this positive evolution, we are pleased to confirm the organization of an event that will merge the WFS workshop with the AO workshop week: the 5th edition of the “Wavefront sensing in the VLT/ELT era + AO workshop week” to be held in Nice, from October 13 to 16th, 2020.
SPIE Conference, new date

On-sky correction of non-common path aberration with the pyramid wavefront sensor
The paper deals with with the on-sky performance of the pyramid wavefront sensor-based Adaptive Optics (AO) systems. These wavefront sensors are of great importance, being used in all first light AO systems of the ELTs (E-ELT, GMT, and TMT), currently in design phase. In particular, non-common path aberrations (NCPAs) are a critical issue encountered when using an AO system to produce corrected images in an associated astronomical instrument.
