TL;DR: However pertect an adaptive optical system can he, it win never tuiiy correct tne image as discussed by the authors, and the effects of non-isoplanicity are directly related to the height of turbulence layers.

TL;DR: A method for testing the surfaces of large mirrors has been developed at the National Astronomy Observatories (NOAO) to be used even when conditions of vibration and thermal turbulence in the light path cannot be eliminated, and was shown to have a sensitivity equal to a Foucault test.

TL;DR: In this article, the authors describe the modifications to the CFHT, Hokupa'a 36 system that were necessary to accommodate the larger 8 meter aperture of the Gemini Telescope. And they compare the performance at the telescope with that predicted.

TL;DR: In this paper, the deconvolution of partially adaptive optics corrected images is proposed for high photometric precision object restoration, which takes into account the noise statistics in the image, the imprecise knowledge of the point spread function (PSF), and the available a priori information on the object (spatial structure, positivity).

TL;DR: In this paper, a program based on the solution to the Poisson equation is applied in order to reconstruct the wavefront, using long-exposure CCD images of the beam cross-section on either side of the telescope focal plane.
