Adaptive optics using multiple laser guide stars

There is a great article on the SPIE website by Christoph Baranec about the about new method to improve adaptive optics using multiple laser guide stars Adaptive optics work by canceling out the effects of air turbulence.

We have shown that the MMT’s laser-GLAO system reduces the atmosphere’s blurring effects over wide fields of view, demonstrating the reduction of stellar image widths by as much as 53% in the near-IR, and uniform correction over a 110 arcsecond field of view.

Check it out it is a good read.
