Modal control using a deformable mirror for adaptive optics
TL;DR: In this article, the control of a deformable mirror for an adaptive optics system that is implemented at the University of Victoria is described and a discussion of sample point lay out to detect a 2D polynomial is provided.

Zernike polynomials and atmospheric turbulence
TL;DR: In this paper, a Zernike representation of the Kolmogoroff spectrum of turbulence is given that provides a complete analytical description of the number of independent corrections required in a wave-front compensation system.

The possibility of compensating astronomical seeing
TL;DR: In this article, the effect of a number of turbulent elements leads to an unsteady enlargement of the image, perhaps with some irregular shifting in position, and the seriousness of this is evident when one realizes that ideally the 200-inch Hale telescope is capable of giving diffraction images of stars about %0 oi a second of arc in diameter, yet the size of the "seeing image" produced is in the range j4 second to perhaps 5 or 10 seconds, being about 2 seconds in diameter on the average.

Pupil plane wavefront sensing with an oscillating prism
TL;DR: In this paper, a pupil plane wavefront sensor is described, which is able to image on a single detector four images of the pupil, containing information on the gradient of the incoming wavefront.
