Abstract

We present the status of the site-characterisation campaign that has been started to aid the development of new adaptive optics systems at the Mount Stromlo Observatory. Our goal is to use a particularly designed stereo-SCIDAR system that uses a roof prism to separate beams from a double-star system to obtain two isolated pupil images on a single detector. Currently, the instrument is partially finished and operates as a generalised SCIDAR. The first results and their analysis are shown. We see that the instrument is working as intended: the data shows no sign of harmful artefacts and the atmospheric profiles follow expected patterns. In addition, we show a comparison of two possible methods to post-process Stereo-SCIDAR data: classical SCIDAR approach and a peak-detection based algorithm. Both algorithms agree on the broad features of the turbulence, but the latter is able to reach finer altitude resolution.

Conference

Conference	5th Adaptive Optics for Extremely Large Telescopes, AO4ELT 2017
Abbreviated title	AO4ELT5
Country/Territory	Spain
City	Tenerife, Canary Islands
Period	25/06/17 → 30/06/17
Other	The fifth Adaptive Optics for Extremely Large Telescopes (AO4ELT5) meeting will be taking place in June 2017 at the Hotel Botánico in Puerto de la Cruz, Tenerife. One of the major challenges that face the future extremely large aperture telescopes (ELT's) is adaptive optics, and the goal of the meeting is to gather specialists to review and discuss the latest developments on this field. The topics of the conference include ELT’s current design in terms of AO systems, related instruments and science goals, and also pathfinder projects planned or implemented on existing telescopes, including solar telescopes, which provide relevant results for the next ELT’s design phase. Special attention will be given to new developments in several areas, such as mirrors, laser technologies, wavefront sensing and control, and new post-processing tools required to increase the image quality and increase the scientific return of the instruments.
