Modelling and Simulation for Adaptive Optics workshop 2014
This was held in Durham, UK, on 18-19th September 2014
Note: This workshop was held straight after an atmospheric turbulence profiling workshop, for the convinience of those interested in both areas.
Simulation and modelling of adaptive optics systems forms a crucial stage in the system design process, and for the forthcoming ELT systems will be essential for understanding operational behaviour once these systems come online. Techniques used for modelling vary widely across the community, and modelling of these sophisticated instruments can be full of challenges.
The purpose of this workshop was to gather together international AO modelling and simulation experts in order to share and exchange experience regarding the design and use of these modelling tools. Such shared experience can be used to improve the quality and usability of these tools. As such, the workshop was aimed at both those who author such tools, and the end users. Although the workshop is focussed principally on astronomical AO, attendance of participants from non-astronomical areas was welcome and indeed encouraged to allow cross-discipline discussions to take place.
The workshop featured presentations and round table discussion sessions.
