Abstract

The proposed Extremely Large Telescopes (ELTs), including Giant Magellan Telescope (GMT), are limited by optical distortions introduced by the Earth's atmosphere. These distortions will be partially compensated by the use of Adaptive Optics (AO), optomechanical systems that can measure the incoming wavefronts of light from celestial objects and rapidly apply an appropriate optical correction using active optical elements, typically deformable mirrors. In this work, we will report the results of the characterization at the focal plane of wavefront images given by different Zernike modes.
