Left Side AO system calibrated

Last week, Vanessa Bailey, Vidhya Vaitheeswaran and I aligned and calibrated the LBTI wavefront sensor on the left side of LBT. This involves putting a retroreflector at prime focus and using an artificial source to measure known deformation of the adaptive secondary with the wavefront sensor. With the help of Alfio Puglisi and Enrico Pinna, we successfully calibrated the system to correct up to 400 K-L modes. The graph below shows an analysis of the AO performance for the 400 modes. The red line shows artificial turbulence introduced into the system, and the white line is the residual left (in nm RMS wavefront error) after correction.

We also calibated the system for faint stars, so that we should be able to lock on guide stars down to R=16-17, based on experience with the FLAO system.

Phil, thank you for giving us information about your research! I read regularly your post! I am interested in the optics field. <a href="http://www.londonremovals.co.uk/moving-company.htm">London</a>
