A HISTORY OF ASTRONOMICAL OPTICS IN FRANCE [PDF]

Journal of Astronomical History and Heritage, 2022
In this paper, we explore the advances made in France in astronomical optics. They were quite important in the seventeenth century thanks to Mersenne, Auzout and Picard. Progress in the eighteenth century was less remarkable and many instruments had to be imported from England, but in the following century the developments were again significant thanks

Astronomical adaptive optics in parameter space

Optics Letters, 2000
We present a general, undiscretized formulation of astronomical adaptive optics that encompasses arbitrary guide star sources and deformable mirror configurations. It is shown that wave-front measurements can be represented as samples of an integral transform of the turbulence perturbation and also that the desired information for adaptive correction ...

Differential adaptive optics for astronomical interferometry

Applied Optics, 1991
Sometimes it suffices to make the wave-front distortions across individual telescopes equal rather than zero. This leads to the concept of differential adaptive optics.

Astronomical science with adaptive optics

Frontiers in Optics 2004/Laser Science XXII/Diffractive Optics and Micro-Optics/Optical Fabrication and Testing, 2004
In the past five years, astronomical adaptive optics systems have begun operation on the world's largest ground-based telescopes. This talk discusses the considerable scientific benefits of astronomical adaptive optics, and highlights some of the exciting new scientific results from adaptive optics systems on 8 - 10 meter telescopes.
